Has anyone been given doxycylcine for mycoplasma congrol or arthritis symptoms. I tried this for 3 months - on a low dose - my family doctor made me sign a disclaimer - and I found it helped tremendously. Which made me think that there is also some inflammation happening with FM. Unfortunately as the literature on it was so spare he would not renew the script even though he was amazed at how well I was doing. If there are any doctors on the board I would love to hear from you.
