The risk of pain and fatigue after three weeks of Lyme disease treatment
Researchers at John Hopkins describe the risk of pain and fatigue after three weeks of treatment with doxycycline for an erythema migrans rash. According to the article published in Archives of Clinical Neuropsychology, 23 of 107 patients (21%) had a high fatigue total score and 33 of 107 patients (31%) had a high pain score. Only 5 of 107 patients (5%) had a high depression total score.

The cut-offs for fatigue and pain were chosen to reflect clinically significant levels of that symptom based on the literature. A cut-off of 36 or greater was chosen for the Fatigue Severity Score (FSS) to indicate “high fatigue symptoms.” A score of greater than 3 was chosen for the McGill Pain Scale to indicate “high pain symptoms.” A total score of 13 or greater was chosen for the Beck Depression Inventory as indicating clinically significant symptoms of depression.
There were a substantial number of patients with a high level of symptoms immediately after completion of the three weeks of doxycycline. “Thus by the end of standard antibiotic treatment (Visit 2), those with high (clinically significant) symptoms of fatigue, pain, or depression continue to have impact on life functioning up to 6 months later,” according to Bechtold from the Department of Physical Medicine and Rehabilitation, Johns Hopkins University School of Medicine.
The researchers identified 6 individuals that suffered from Post-Treatment Lyme Disease Syndrome (PTLDS). The authors used the IDSA case definition of PTLDS as follows:
“a documented episode of early or late LD with post-treatment resolution of objective signs of LD, but continuation or subsequent onset of symptoms of fatigue, widespread musculoskeletal pain, and/or complaints of cognitive difficulties. These subjective symptoms must be continuous or relapsing for at least 6 months following completion of treatment and must be severe enough to reduce the patient’s functional ability.”
The remaining patients with severe fatigue and pain did not meet the PTLDS criteria. It would appear that studies of PTLDS clearly underestimate the morbidity associated with Lyme disease.

5 weeks after bite, I still have a tiny raised scab surrounded by red skin. Thinking of seeing my dermatologist who might excise it completely. Your thoughts? Thanks, Robin
It could be just the chemical and physical reaction to the tick bite rather than an infection.
I am not getting that this proves that the pain and fatigue were caused by the ABX and not the infection unless the patients studied had zero fatigue, pain and depression at the initiation of the ABX treatment. I continued to decline after the 3 weeks of ABX until I found a Lyme doc who prescribed a combination of ABX that was appropriate. It took 4.5 YEARS of treatment before the symptoms that had all presented BEFORE ABX treatment began to resolve. Yes this is hard but denying treatment with multiple antibiotics for those who can handle it is criminal. In response to Mary Ann above, your Lyme must not have been close to what I was dealing with. It would have killed me and I was willing to try any treatment that had a chance of saving my life.
By the IDSA definition, a diagnosis of PTLDS is conferred after objective resolution of the initial Lyme disease infection, whether it was caught early or late. If LD symptoms never fully resolve, or wax and wane without complete resolution, despite active treatment for a period of many months or years, what is the the term for this clinical picture?
It has not been defined
The Hopkins authors results confirmed what many of us know in practice, that there are patients with severe fatigue and pain using standardized measured despite 3 weeks of treatment. These studies confirm the obvious.
I was on doxy then biaxin for a total of about 15 months. I still have fatigue and some other symptoms. Is this a permanent side effect or should I be looking into further treatment? I do take supplements and Chinese herbs for symptoms.
Your treatment would not address Babesia. It is also important to rule out other illnesses.
I agree with your concern.
After 3 months on abx for borreliosis the pain and fatigue have never gone away. It’s been 5 years so far. I also thought I was going to die from the abx treatment. It was worse than the Lyme.
It can be so difficult.
