i was prescribed sumatriptan 50mg (imtrex) by my doctor for migraine attacks. The first time i took a pill, my face swelled up within a few minutes- within 5 it was bright red, puffy, hot to the touch and i was in absolute agony. My eyes were burning and slightly puffy and my muscles felt weak and floppy. worst part my head still really really hurt😕!! has anyone else had this happen?
