My boyfriend is 6ft, 185lbs and otherwise healthy, yesterday at 3:30 he had a vasectomy and we've been icing and resting since. During the evening he took a hydrocodone 5 at 5:00p.m. & again at 1:45a.m. and today at 10:30 two over the counter tylenol, since 3:00a.m. he's had nausea, dizziness and a near fainting episode without any fever, is this common?
