Pain
"I have moderate to severe knee pain; awaiting  knee replacement surgery. I tried lortab 10 mgs but developed allergic reaction (itching). Md prescribed panlor ss. I never got the chance to see if it really worked because I also had a reaction to it. The only thing I can figure out is that I have developed an allergy to codeine after all these years at age 52. That is the only common ingredient that I can think of"
