Pain
"I was prescribed 1-2 of the 75mgs every 4-6 hours as needed for severe shoulder pain, due to rheumatoid arthritis and an undiagnosed muscle disorder (something similar to fibro, but not yet diagnosed officially). I took 1 pill and after about 45 mins, felt no relief, so I took another.  After about another 30-45mins, I started to feel really messed up in my head, fuzzy, dizzy, not too bothersome until I started having heart palpitations, very scary! I went to bed about 2 hours later and had major hallucinations (this has NEVER happened to me on any other drug)  I have taken many pain killers, both narcotic and non-narcotic, so my experience is vast, and I have never encountered side effects like this.
