So I'm four days into my copaxone. Yesterday my jaw started hurting. I ignored it assumed I had done something to myself, and just didn't remember. Now it's to the point where i can't open my mouth any further than what it takes to sip on a straw. Anymore than that I'm met with blinding pain and resistance. Is this a side effect of the medicine that I've ovrlooked or am I just being paranoid?
