"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&#039;ve had no problems achieving an erection, but have not been able to &quot;finish&quot;. that is the only side effect i&#039;ve experienced to far. i am taking it with naproxen as an anti-inflammatory."
