Had dental surgery (an implant), Dentist gave me an Rx for Lortab and received a generic at the pharmacy. Dentist's instructions was to take the Lortab as his painkiller was fading to prevent any difficult pain. Took the tablet, started feeling sleepy (early afternoon) and git into bed and immediately fell asleep. When my wife checked on me, instead of expecting me lying quietly on my back. She found me in constant motion, twisting, turning one side to the other--rather hectic. When I awoke, I found sharp pains in the back of my head, across my back, and down my right side to my knee. After medical questioning and an MRI of my spine, the opinion was that I had pinched one or more nerves. This happened 2/2/08 and still with me 3/14/08. I have PT 2X a week with some relief each time, Still in pain!
