Tramadol
"I was in a car wreck with whiplash. eye sensitivity, pain from mid back of head down spine to below shoulder blades, and out to both shoulders, and involving full lumbar area. Doctors put me on this stuff for the intense pain. I took it for two days, hoping it would help. OMG it double-downed my pain. I wanted to kill anyone and everyone, walls, sheets, everything that got in my way or accidently pissed me off. Called the doctor and literally growled at her about how much I hurt. I expected double pain to some extent after that kind of a shake up but this was beyond acceptable and as soon as it was out of my system I still hurt but was back under 10 on that 1 to 10 scale."
