Thank you, I was diagnosed with MS almost 13 years ago, FYI, anyway dont think this symptom has anything to do with MS. I have had a sore, reddish tongue, and taste has changed like metal taste lately.. I fell almost 2 weeks ago and had severe hamstring strain on right leg, I was taking a pain (oxy/perco.) I have never taken that type of pain med before, so not sure if that may have a side effect of my symptoms? I finished the medicine for pain 4 days ago.My eating habits, etc.. has not changed, this may be a question for my dentist?
