Tramadol
"My doctor put me on this for a nerve condition which typically leaves me in dull pain, with occasional fierce spikes in pain. He noted that it is a "very powerful painkiller" so be careful. I took one, waited an hour or so, nothing. Took the second one, and again now almost 3 hours later I feel 100% the same, the pain has not been reduced at all. I took 1 200mg advil, and felt a minor amount of relief, so this is about the power of maybe a baby aspirin. Hardly a "powerful painkiller. I thought maybe it was just me, but after some research I see I am not alone. I think this medicine is nothing short of pharmaceutical grade snake oil. I will be going back to my doctor to rid this hoax in a bottle."
