So the blood work came back positive for Lyme - lovely. I so don't have the time or energy to deal with this complication in my life right now!
Hey - you might get better after the 21 day course of antibiotics. But, like bibliothecula says, if you are NOT better after the 21 days (or if you get worse on day 25) go right back in and demand more antibiotics.
I got Lyme back in 1999 (I think), when it was only a 10 day course of antibiotics. I felt better on day 9, but by day 14, I was wicked sick again. I bounced from doctor to doctor trying to get more antibiotics for months. The dermatologist said I had lyme and wasn't comfortable treating it. So she sent me to the infectious disease specialist, who at the time, didn't think it was Lyme and thought I had an autoimmune disease. The rheumatologist (sp?) said that she didn't think it was likely that I had an autoimmune disease since my history suggested that my joint pain was associated with my sudden illness - I was backpacking in June, sea kayaking on July 1st, then laid up in bed on July 5th. You don't need to be House to figure out that it ain't lupus. It's an infection.
Finally, my mom (an RN) pilfered a month's worth of tetracycline for me. It did the trick, although it took me a bit longer than a month to get my strength back.
