muscle spasm
"On Thursday 04/27/17, I decided to have my PCP prescribe a med for my chronic lower [right] back pain. Once she determined I may have a strained muscle, she prescribed Methocarbamol 500 mg tablet along with Meloxicam 15 mg tablet. I took the initial dose after my 7:30 pm dinner. And a short time after, maybe 15 minutes, I began to have moderate chest pains, and a dulled heart beat. This lasted only a few minutes, not long enough to warrant a visit to the emergency room, I gathered. The following morning, I woke up to a swollen face [side effect of meds]. Friday 04/28/17, I informed my PCP's office I do not plan to take any more of either med.

Just wondering how long the facial swelling will last."
