Last year about this time I was searching the posts of Lets run to figure out why I had been having all of this back trouble. I thought it was piriformis syndrome and ran through XC with the help of lots of anti-inflammatory drugs although I was just tired all the time. After the season was over, I was dianosed with Lyme disease and have been on antibiotics since then incuding doxycycline, IV rocephin, and now ceftin and hydroxychloroquine. I've been able to come back to running and am almost completely better but I have learned way too much about this poorly understood disease.
-less than 1/2 get the "bulls-eye" rash
-most people never recall being bitten by the tick (since most deer ticks feeding are nymphs the size of a poppy seed)
-symptoms can be different for everyone (often begins with flu like symptoms then progresses through muscular, arthritis, or neurological problems if not caught early)
-the longer you have it before it is diagnosed, the longer treatment will have to be
-the CDC reported 25,000 cases last year but it is estimated that 10 times that many occur due to missed diagnoses attributed to other disease like MS, ALS, and "running overuse" as with me
-some people are not cured by the standard short term antibiotic treatment so if symptoms never go away or return, don't let then tell you that you were "re-infected." Go back on antibiotics.
-coinfections can be transmitted by ticks in addition to LD
-If left untreated, LD is not fatal, but can lead to severe cognition, memory, neurological, arthralgia, and muscular problems.
-email me if you have any questions, healthboards.com has a great forum for LD as well
