Why Lyme Disease Is Often Missed in Medical Training
WHY DO DOCTORS MISS LYME DISEASE?
SOMETIMES…
IT WAS NEVER TAUGHT.
Lyme disease is one of the most commonly missed diagnoses today—and part of the reason is that many physicians were never trained to recognize it.
Understanding how Lyme disease entered medical practice helps explain why it is still missed today.
For a broader overview, see the Lyme disease symptoms guide.
A Disease That Wasn’t Yet on the Radar
During my medical school, graduate school, and residency, Lyme disease wasn’t even on my radar. That’s not surprising, given that I trained before Lyme disease had fully entered the medical lexicon.
At the time, Lyme disease was considered a rare and localized condition, limited to a few regions in the Northeastern United States.
Medical training focused on well-established diseases—heart disease, diabetes, and infections like tuberculosis—leaving little room for something seen as obscure and geographically limited.
A Rare and Localized Disease—Until It Wasn’t
Early reports of Lyme disease emerged in the 1970s and 1980s, with clusters of cases in Connecticut and surrounding areas.
But it took years before the condition was widely recognized—and even longer before it became a routine part of medical education.
Today, Lyme disease is the most common vector-borne illness in the United States, with hundreds of thousands of cases annually.
A Turning Point: Recognizing the Pattern
In 1987, I began seeing patients with symptoms that didn’t fit neatly into any diagnostic category—fatigue, joint pain, and neurological issues.
These were not rare cases—they were missed patterns.
These patients had seen multiple specialists, undergone extensive testing, and still lacked a clear diagnosis.
It was in these cases that the pattern of Lyme disease became clear.
Lyme disease can present with vague, non-specific symptoms and is often referred to as “The Great Imitator.”
Why Lyme Disease Is Missed
- Non-specific symptoms that overlap with many conditions
- Variability in presentation from patient to patient
- Limitations of standard testing
- Gaps in earlier medical training
For more on testing limitations, see why Lyme tests can be negative.
Medicine Evolves—But Training Lags
Medicine evolves—but training often lags behind emerging diseases.
Lyme disease highlights how conditions can shift from rare to widespread within a generation.
In some cases, what was not learned during training continues to influence diagnosis decades later.
The Importance of Listening to Patients
Lyme disease reinforces a core principle of medicine: listen to the patient.
Symptoms may not fit neatly into predefined categories, and diagnosis often requires recognizing patterns rather than relying on a single test.
Sometimes the most important clue is the pattern—not the test result.
FAQ: Why Lyme Disease Is Missed
Why do doctors miss Lyme disease?
Because symptoms are often non-specific, testing has limitations, and some physicians were not trained to recognize Lyme disease.
Was Lyme disease taught in medical school?
It is now, but many physicians trained before Lyme disease became widely recognized.
Clinical Takeaway
Lyme disease was not always part of medical training, and that gap still affects diagnosis today.
If Lyme disease is not considered, it cannot be diagnosed.

I have lived in Australia all my life.
Got bit by a tick at the age of 18.
2015 found a naturopath and sent blood to Germany.
Come back positive for Lyme disease.
The suffering from Lyme disease i might have well been dead.
As not one doctor or infectious disease specialist believed me.
I finally found a doctor that knew how to read the Germany test results.
I never gave up and so lucky I found her and now I also have a Specialist which both help me with my illness.
And I have 5 chronic illnesses
I am now 54 this year and just get through each day as I can.
I fight for every day as I have one beautiful son that will be 25 this year.
I live for him every day.
Until I can’t go anymore.
I bless and pray everyday for any other that has Lyme disease.
Thanks for the blessing. I hope you get better someday
Im the same age as you Kim and in Tasmania , 4 years ago i got insanely sick very quickly from a tick bite on the back of my neck . Encephalitis, a 14 month migraine , crushing chest pains , lost my memory, i was a full zombie and said good bye to my wife and boys a few times I was sure i would die .i went to hospital in ambulances , cardiology , CT scan’s , infectious diseases clinic , numerous blood tests but they would never test for what I asked , got treated like rubbish , like i made it up which shocked and upset me . I realised I had to treat myself so read everything i could about tick illnesses and had more supplements than a witches larder . I got covid about 20 months later and hit it hard with ivermectin and after It disappeared I started getting better quickly , now 2 years later im 90percent better on average , i still get mild head aches and occasional chest pains . I take sativa cannabis oil cbd, thc at night and ivermectin once every 4 months and life is good . Not saying the same thing will work for you but dont give up hope , if i could get better you could too , you just need to kill the bacteria, virus and parasites, if you have not tried ivermectin id give it a go
I am glad you are 90% better.
Your lastest articles are absolutely wonderful! I wish there were more Lyme literate doctors in the world. I have been struggling with PTLDS for years. In the past I was a patient of yours, during that I actually felt ok. Unfortunately because of the distance I couldn’t continue my treatment at your practice. I would be eternally great full if you could refer me to a Lyme Dr. in CT.
Thank you.
I am glad you felt better for awhile. I hope you get better again. I am not familiar withe the professionals in Connecticut. You may find it helpful to check with GlobalLymeAlliance or ILADS for names if your primary can’t arrange someone for you.
Bless you for managing your horrid disease without the assistance of all those ignorant. pompous so called” Dr.s”. There are so many of us that we have lost to death, assisted suicide and just plain suicide! My brain roars when I hear stories like yours…Take care..Sometimes, it’s too much to take just one day at a time…for the sake of our sanity, we must take it one minute at a time.
