muscle spasm
"I tryed norgesic for 2 weeks 3 times a day. It was for a bad muscle spasm im my back, was hard to breathe. I swear norgesic is a placebo.It  did nothing at all for me...Nothing. Worked as paracetamol at best dose no better imo. Told the doctor of my opinion and was given Valium  (diazepam) 5mg. That worked amazingly. I felt it working the whole time. With the valium it took me 2 weeks to recover. Im EXTREMELY surprised to see so many people say norgesic it worked for them, But glad it did. 
I don't usually give feedback  /- however I truly don't think this compound works."
