I'm having a really awful day today, and I'm not sure how much is fibromyalgia (or CMP, if I have it) and how much is a reaction to my second shot of Avonex, which I take for my MS. The most common side effects of Avonex are flu-like symptoms and body aches. I woke up yesterday in the wee hours with pain in my jaw, teeth and ear on the right side. I was wearing the NTI device I wear for TMJ dysfunction (which I also have), and this pain seemed different from TMJ pain I've had in the past. I called my dentist, and he said it sounded muscular. He made a couple of symptomatic suggestions and said to come in on Monday if the pain continues. (My dentist is a long-time friend, so I don't think he was just trying to get rid of me. Anyway, I had my Avonex shot in my right thigh about 6:30 p.m. last night, taking some painkillers to deal with the side effects. But the painkillers didn't help much, and by 10 p.m., I had extensive pain. I took a Fioricet and 200mg of Neurontin when I went to bed, and that helped for a while, but I felt very woozy--I think from the butalbital in the Firicet. Despite all the meds, I had trouble sleeping and woke up still hurting. I could barely eat anything this morning and start feeling queasy, too. At least that eased after I went back to bed, and I was able to take a bit of a nap, which helped, I think. I took Fioricet again--which has never bothered me in the past--and once again I felt woozy, a bit dizzy, and sometimes as if my eyeballs were moving around without my wanting them to! (I think that might be nystagmus, a fairly common MS symptom, but one I haven't experienced in the past.) All of this is so confusing. I know the important thing is just to find something that works, but it's hard to know what to try when you can't figure out what's causing the pain. The reason I'm posting this is to ask: (1) Could this be a fibrmyalgia flare? (I'm new to fibromyalgia and don't know what a flare looks or feels like.) (2) Does anybody else have jaw pain with intermittent piercing pains that feel like something inside the ear itself? (3) Does anybody else get pain aroung the top of the shoulder, radiating down the arm? It kind of feels as if I had a shot in the arm, but my shots have been in my thighs. My right arm is so sore I feel as if I want to put it in a sling to limit the movement. I don't know whether this is fibro or not, but this is about the worst pain day I can remember. --Laura R.M.
