question: I am a 41 year old female with RA. I have been taking Methatrexate for several years now (8). It has destroyed my teeth. Right now I am experiencing terrible pain on the right lower side of my head, behind my ear. Could my teeth be causing this? I can feel the pressure start building up and release in my head. Blood pressure ran a pretty consistent 136/80 last night when the headaches started. Thanks for your help.S Musick
