I thught I would have a nice, relaxing day at the pool. I swam for awhile, then was going to lay on the lounger. When I laid back, I had a severe pain on my spine. I just thought towel bunched up, moved around, and finally gave up and laid on my stomach. I spent around 4 hours in and around the pool. Even after I came upstairs, everytime I leaned back on a chair or couch, my back hurt. Living alone, it takes a contortionist to see my back. I finally scrunched around enough with the aid of mirrors, and see a bruise, about 2 inches long, right on my spinal column. It is really painful. I just applied a lidocaine patch, took Tramadol, and am hoping it will quit hurting. Has anyone ever had a herniated disk that actually caused a bruise on their back? I did not hit it, fall, or remember doing anything that might have caused this. How long before I panic and call my doctor or go to emergency room? I really don't want to do that, but am flying next Sat, and need to be in shape to get on the airplane. Any suggestions for an immediate fix appreciated. Don't want this to spoil my vacation.
