lyme disease, arthritis
"I have been taking Hydroxychloroquine, 100 mg for several years off and on for chronic lyme which cranked up arthritis soon after being bitten approximately 50 times on the first exposure. This seems to help once my body has adjusted. Often I can feel that it must be working because it will seem to bring on a Herxheimer reaction now and then but overall, this drug has worked well for me."
