Eh, tramadol... I was scripted this after I had an injection of it in the past (by the way, it ain't in the arm!). First time I had it IM, it worked really well. So I asked for a script to cycle off other opioid medications. It isn't really like what most people that enjoy opiates such as hydrocodone or the like. It does seem to have some therapeutic properties to relieve pain. Now the down side. I was scripted only two 50 mg a day. First day went well, second day was fine too. Now the third day I awoke to what can only be described as pure agony. I had a massive, throbbing headache. Every muscle and bone was aching, quickly cycling to hot and cold. I couldn't keep anything down, vomiting all morning while experiencing vertigo. It passed once I could get 25 mg of tramadol down. Called the doctor and she said to stop taking it immediately, that I was experiencing the odd serotonin syndrome. Not fun at all. I always caution people to be careful with it, as it can also induce seizures and have the experience I went through.
