Why Doctors Miss Lyme Disease: Evidence From Clinical Cases
Doctors may miss Lyme disease despite recognizable symptoms
Diagnostic uncertainty can delay treatment decisions
Clinical experience and pattern recognition matter
Investigators asked clinicians to review 11 cases of Lyme disease to determine whether doctors may be reluctant to diagnose Lyme disease. They found that only 5 cases contained Lyme disease on their differential diagnosis list, and only 2 cases were coded as Lyme disease, writes Tulloch.
Patients often ask how doctors diagnose Lyme disease, whether there is a reliable blood test, and why Lyme disease can still be missed when symptoms are present. These questions highlight the gap between clinical presentations and diagnostic certainty.
The findings highlight an important question: why do doctors miss Lyme disease even when clinical clues are present? Delayed recognition, uncertainty about testing, atypical presentations, and concern about diagnostic accuracy may all contribute.
Testing for Lyme disease can be challenging because diagnosis often depends on symptoms, exposure history, physical findings, and laboratory testing rather than a single definitive test.
Understanding why clinicians miss opportunities to diagnose Lyme disease may help reduce delays and improve outcomes. Learn more about delayed Lyme disease diagnosis.
Clinical Cases Showing Why Doctors Miss Lyme Disease
The Lyme disease case presentations varied:
- Classic erythema migrans (EM) rash
- Borrelial lymphocytoma of the ear lobe
- Acrodermatitis chronica atrophicans (ACA) with peripheral neuropathy
- Bell’s palsy following an “insect bite”
- Recurrent synovitis of the knees
- Multiple EM rashes after walking in Dartmoor
- Heart rhythm abnormalities
- Fatigue, post-exertional malaise, anxiety, headaches, and memory issues with a positive Lyme disease test from an international lab
- Fatigue, arthralgia, poor ability to concentrate, myalgia, mood swings
- Non-engorged tick attached to scalp
- Poor fine motor movements and a rash occurring 2 months previously at scout camp. (This patient had not been treated with erythromycin.)
Why Clinicians Hesitate to Diagnose Lyme Disease
The physicians cited several reasons for their reluctance in considering Lyme disease as a diagnosis.
- “If I can’t diagnose, I will pick the main symptom to code. I will always do this unless I’m almost [100%] positive of the diagnosis. Sometimes, if I’m really not sure, I will write everything in free text and not code anything.”
- “Lyme disease is a possibility here. But I wouldn’t leap to it without a history of a tick bite.”
- “I would never write Lyme disease on a patient’s record until I had a positive lab diagnosis. I’m wary because of potential litigation, and I don’t want to cause problems for future doctors treating that patient.”
- “I won’t code Lyme disease until they’d seen an NHS specialist. I’d be very suspicious if it [laboratory results] was a ‘high street’ or ‘internet’ lab, so I would arrange serology to be sent to a local lab.”
Several comments suggest that diagnostic uncertainty may influence whether clinicians diagnose Lyme disease, particularly when blood tests are inconclusive or presentations appear atypical.
Diagnostic uncertainty is one reason patients may experience Lyme disease misdiagnosis or delayed care.
Experience Influences Recognition
Some doctors were more familiar with Lyme disease through their own experiences.
- “This is a tick; I’ve been bitten many times before.”
- “I had a patient diagnosed in the last couple of months; a child with non-specific knee pain. We initially suspected an infected knee joint. He’s now been successfully treated and has been fine since.”
- “There are so few [Lyme disease] specialists across the country. A friend of mine has Lyme, so I know the difficulties.”
Clinical familiarity may influence how quickly physicians recognize symptom patterns, especially when presentations overlap with neurologic, rheumatologic, or nonspecific illnesses. See more on neurologic Lyme disease.
Study Limitations
The study enrolled only 8 general practitioners and involved case reviews rather than actual patient encounters. Some physicians were unable to complete their evaluations because of time constraints.
These limitations make it difficult to determine how frequently reluctance to diagnose Lyme disease occurs in clinical practice.
Frequently Asked Questions
Why do doctors miss Lyme disease?
Doctors may miss Lyme disease because symptoms overlap with many conditions, presentations vary widely, and testing limitations can create uncertainty.
Does Lyme disease always require a tick bite history?
No. Many patients do not recall a tick bite, which can make diagnosis more difficult when clinicians rely heavily on exposure history.
Can Lyme disease be diagnosed without a rash?
Yes. Many patients do not develop or recognize an erythema migrans rash, making diagnosis more challenging.
Why does delayed Lyme diagnosis happen?
Delayed diagnosis may result from atypical symptoms, negative early testing, competing diagnoses, or low clinical suspicion.
Can physician experience affect Lyme diagnosis?
Experience and familiarity with Lyme disease patterns may influence recognition, particularly in patients with atypical or multisystem symptoms.
Clinical Takeaway
The study suggests that diagnostic uncertainty may influence how physicians evaluate and code Lyme disease presentations.
Improving recognition of atypical symptoms, testing limitations, and diagnostic patterns may help reduce missed opportunities to diagnose Lyme disease earlier.

I have had the medicine for Lyme disease three times. Each time it made a tick bite that was getting progressively ugly vanish.
I have had to stop going into the woods in back of my house.
The third time it was not my doctor but some clinic and I had to talk the doc into prescribing, then he wanted to prescribe one pill instead of the standard regimen, I had to explain how the disease hides by partly going dormant.
I am lucky I heard and read a lot about this disease before I had my problems, my sister has it, in later stages you can’t get rid of it.
I am sorry you and your sister are having such difficulties.
My sister also has Lyme disease and Dr’s in Nebraska don’t (at least a few years back) treat that here- they don’t believe it exists.
I, after taking immunizations for a gov job and going hiking in the mountains soon after, was then bit by something. A mostly red circular rash around it, white smaller interior. Maybe a 1 1/2 inch diameter.
A couple of months after the bite, that I presume was a tick- the thing was attached to me- I thought it was mud and pulled it off. However, my legs started to feel heavy and I felt as if I was dragging them along. I went to see my internal med Dr, who refused to give my a Lyme test. He said they don’t believe Lyme is in Nebraska. My sister got hers by the stream in her back yard, but I got mine in Colorado. He still wouldn’t listen to me. He refused to take any lab.
Now, my sis heard of it and said she insisted he provide the lab work. He refused, citing “it’s political “. I don’t know what that means, and he wasn’t telling me more.
The symptoms continued, I started having major cramps in my muscles, sometimes for hours (still true today-still no dx) and vomiting spells. That had never happened to me before. My sis had to go to Missouri for a dx and tx for years.
My sis went out and purchased the test kit and told me to take it to the lab, which I did- had the physician give it to them and prescribe it. He said the nurse would call w results when they came in. 3 weeks later, still no call, so I called the office. They said they lost it. No offer to retake or to refund fir the cost of it. It’s political alright- in their office.
I was studying nutrition so did a deep dive in foods that can heal the body. It took about 2.5 years to be able to walk freely, but theweakness and fatigue never went away.
I fell a couple times, torn muscles around my knee, finally agreed to a cortisone injection in my knee a year later, as no Dr would treat (I guess) bc I was uninsured.
I never realized the heart rhythm disturbances could be from Lyme. Mine came a couple years after the bite. Anxiety was out of this workd- I don’t usually suffer from that. Also, I was working and going to school, nearly full time each and driving 2.5 hrs 5 days a week. Crazy busy, trying to get help but nobody would.
Went back to Dr saying I really needed some help. He didn’t even look at me, he was mire interested in clearing pics off my phone so he could install an app and told ne to walk more. He wasn’t lustening- I couldn’t! But I wanted to.
Fast forward a couple years…I was working at my new FT job in Hospital and LTC when covid began. It got crazy fast. Staff left, Mgr left, I, as assist to Mgr, had to work 60-80hrs a week, a lot on my feet.
Progressively, the severe body pains set in, my legs developed such terrible cramps in my legs that I couldn’t get out of bed- terribly painful! I had to call my son to bring me a cane so I could use the bathroom. 2 days later, the next one froze up also.
I had gone to ED for the first, w no resolution except a possible infection in the veins, but while he said he should prescribe something for that, he only prescribed zorelto. I’m glad I questioned the 1,000 dollar med. I had paid for a week’s worth and went back to ask the nurse who was also attending that eve what she thought. She asked if a clot was dx. No, it wasn’t. She said she woukd advise against it.
As I waited the 30 days behind schedule my own dr had, I literally stood up from my sofa, lost my balance, tried to correct on one side and twisted my ankle all the way around- trimalleolar fx .
2.5 years fast forward…I still have significant pain and swelling in the joint. Bone pain (had an x-fix), metal plates which I seemed to be allergic to, so they were removed, some screws removed and the bone shaved down.
The crazy covid days didn’t help, but I believe my legs were still impacted by the stinking bite that nobody woukd treat. Still, I get terrible, terrible leg cramps. Why do they not take it seriously?
I reported various Lyme symptoms to 7 doctors spanning 5 years. Two used inferior (unethical tests, I believe) to rule out Lyme. I finally paid, out of pocket, $600 to Vibrant Labs (my blood was drawn by my local doctor and sent to their lab) and $400 doctor fee for interpretation (a total of $1000)! The results showed high zonulin, markers for a chronic inflammatory condition which I was diagnosed with, the crossing of the blood brain barrier and many additional problems. The test showed 14 tick borne pathogens identified as severe or moderate and 42 tickbourne pathogens rated as under control. Interestingly, many of the 42 “controlled” pathogens were in the 8 or 9 range where 10 indicates as problematic and indicative of Lyme disease. I also have a raging E Barr infection, numerous mycotoxins and various resistant pneumonias. After taking antibiotics for 5 months, I now have leaky gut, also proven by the test. All this and I do not meet the CDC criteria for Lyme which is SHAMEFUL! I do meet the alternative Lyme criteria. I have been housebound since July 2021 with excruciating bodily pain and severe fatigue. I have 0 quality of life. I contacted every Communicable Disease Doctor I could find in St. Petersburg, FL and I was REFUSED TREATMENT even when I asked to be seen for the pneumonias and mycotoxins. I do not know how these doctors can legally refuse me treatment. Lyme patients are scorned, told they are liars through action by some doctors, ignored, and DENIED TREATMENT by mainstream medical establishment. I now have an invoice for $17,563 + for upcoming Lyme treatment that mainstream medical refuses to assist with. Naturally, I have had to refuse much of the medical treatment that my Lyme specialist has recommended for me. I will attempt to limit my bill to $10,000 which I still cannot afford! This is a horrific injustice to all Lyme patients.
