Sore jaw symptoms and conditions

a full week after my first remicade treatment, i suddenly developed a very severe headache, followed by a stiff neck, a stiff left arm, a sore jaw where i couldn't open my mouth very far and i could not chew, then developed a fever, chills and itching. It came on fast but also subsided a good bit within about 12 hours. has anyone else experienced something like this, a full week after a treatment?

After jsut 1 pill I had swollen hands, felt like head was swollen but it didin't look like it! Tremendously sore jaw and ears-like a very severe sinus infection. Intense head ache, felt like I was crawling out of my skin, fidgty-yet tired, severe muscle aches in upper body...This was after just one pill. I stopped and I was fine 24 hours later...none of the symptoms remained.

HAVING MIGRAINS, I HAVE A SORE JAW, NOT SURE IF THATS A SIDE EFFECT OR NOT.

TAKE 5 MG 4 TIMES A DAY
WORRIED IF ITS SAFE

OTHERWISE, EMPTIES MY STOMACH FAST, LETS ME GET SLEEP AT NIGHT- VERSES NOT/

NOT SURE IF THE DRUG OUTWEIGHTS THE BAD
