Ask to be tested for viruses like Epstein Barr, HHV6. I have had a viral infection for 6 months now and the inflammation and nerve pain it is causing has been terrible. But taking valtrex has helped me. Its funny even my PT who works with me on my muscle and inflammation issues was amazed that much of it was being caused by a virus, especially the capsulitis.

Couldn' hurt to be tested for for it and maybe it could be causing some of the problems. Some of these viruses get into the central nervous system.
