I was on Famvir and my fibro doc switched me to Valcyte. Something worked because my energy is better than it's been in 8 years. I'm getting severe - I mean severe - neuropathy in every tooth that has ever had a filling as well as caps. I searched online and could only find a few instances of people experiencing this. However, I couldn't find out whether their teeth hurt from antivirals - or if it was the virus itself/ the toxins causing the phenomenon. I don't even know whether it's related to the antivirals. Doctors/ Dentists can't give much help here. I'd appreciate hearing from anyone who has experienced this and determined the cause.
