Hello- I have been told that I have Lyme Disease. I know I was bitten by a tick 28 years ago. I have muscle aches in my thighs and get sleepy (in the evening) not during the day as I hear some people do. My question- has anyone out there ever tested negative in a blood test for Lyme Disease after treatment with antibiotics. I have been on antibiotics for two years now and still test positive. Is it the Lab test or something else?
