Sunday night I was in horrible pain and took 2 endocet 5mg for jaw pain. I have never taken this medicine before it was my roomates, i was out of tylenol so didn't think it would hurt. Well I felt fine that night then the next morning I woke up with a migraine and was vomiting literally the whole day. TuesdayI felt fine except for a slight stomach ache, now Wed. I have horrible stomach pain in my abdomen and bloating. Could this all be from the pills I took? Would the side effects last this long?
