"i was prescribed tramadol for a herniated lumbar disc and sciatica after trying several other painkillers in vain. this is the only painkiller that has given me any relief and i can feel it working immediately. i also take diclofenac and find this to be a great combination. night times are still a problem for me but during the day the pain has significantly decreased. i&#039;ve had a couple of side effects - dry mouth and occasional sweats but i&#039;m willing to put up with them for some decent pain relief at last."
