Lyme Disease
"As a fence contractor I was bitten on the chest by a lyme tick which was incorrectly removed.  I did have an ecchymotic area surrounding the bite but not the characteristic bulls eye erythema migrans rash.  After three months I developed a fever of approximately 102 which persisted for a month.  Weakness,  sweats and phantom sun rashes led me to conclude the strong possibility of Lyme infection.  I began taking doxycycline hyclate which appears to be the best orally tolerated form  of this antibiotic for most people.  I took an initial dose of 200mg daily divided as 100mg q. 12hrs or twice daily.  My fever dissipated slowly over a week and other symptoms went into remission,  some of which were so subtle I did nit attribute them to Lyme."
