Hi Dr., Five days ago I was working out at the gym. I lifted more weight than I should have doing hang cleans (swiftly lifting bar from knee level to shoulders) and felt sharp pain in my right lower back. My back was sore for a day or two and most of the constant pain has gone away. My problem now is, when I lift anything light or bare body weight on my back or sit down, there is more sharp pain. Also, my back will occasionally hurt when twisting. The pain is still focused in the right lumbar region. There is no pain in my buttocks nor my legs. Being the pessimistic person I am, I believe my problem to be a herniated disc. Of course it has been less than a week since the injury, but I would still like your opinion. I am 20 years old and have no history of back injuries. Thanks, Blaise DesChamps
