pain
"I was prescribed tramadol 50 mg for a herniated disc. Two days ago I was not able to move because of the pain, I even had my legs buckle a couple times due to intense bursts of pain. 1 pill will dull the pain to a manageable level, 2 stops it completely. It does make me a little sleepy, but drinking coffee during the day kept me alert enough to work. I've had no problems achieving an erection, but have not been able to "finish". That is the only side effect I've experienced to far. I am taking it with naproxen as an anti-inflammatory."
