What meds or autoimmune disease causes mouth sores?
Being having some mouth pain and then this morning woke up to find what was the cause. I have mouth sores, almost canker sores, in my mouth on both sides and also there are several enlarged taste buds. I am on plaquenil for my RA but no other meds for it except for pain. Does RA do this? I am confused and boy does it hurt, especially when I try to eat! Any ideas?
