### input:
I recently had a tick bite and the doc thought I may have lyme diasease. The blood test came back with a IGM p23 present however not enough bands to indicate a positive for lyme diasease although the doc dis start me on antibiotics because i had a rash at the site of the bite. Now i am fatigued, have alot of joint pain and cramping in the legs. Around the same time I told her I was having pain in me finger joints too. What does the presence of IGM p23 indicate? I also take synthroid for a throid condition and crestor. She told me to stop the crestor for awhile to see if it helps. It did not. Now she is saying I should see a rumatologist (I know spelling)not a doc ok..... What do you think?

Hello. Welcome to Chat Doctor. I am Chat Doctor. Well your concern is genuine. Lyme disease can be caused by bite of tick. Problem with this disease is that it is similar to many other illness and test available for diagnosis shows variable results in many patients. Same is in your case, only one band is not enough for confirmation. You should consult expert infectious disease specialist for this. There is also need to rule out other coinfection like if any. Also, you did not mention which antibiotic you are taking. You should also know that during treatment of Lyme disease some patients show unusual exaggeration in symptoms which subsides after few days.Finally, your thyroid medication will not interfere with this treatment, but you should get your thyroid level done if not checked recently. I hope this will help you. I will be glad to help you further in this whenever required. Wish you a rapid recovery. Please revert with your valuable feedback. Regards.
