"i have severe lower back pain. my doctor had prescribed lortab 10/500 which was effective for a period of one year. i noticed that all though this medication never really killed the pain, it made it tolerable and allowed me to live a normal life. after sometime i had noticed lortab lost some of its effectiveness, and did not want to increase the dosage. doctor prescribed tramadol to replace lortab. i feel it works great and have zero side effects. i use it 3 times a day(50mg) tabs.i was worried about a symptoms of withdrawal from lortab, but none materialized."
