Hi Linda
I find Robitussin Cough and Cold Extra Strength to relieve my jiont pain in only a hour or so. It is the best thing I have tryed. If I take 2tsp 4 times a day for 4 days I am good for days some times or longer. A doctor in Canada told a friend of my wifes to try it and it worked for her. (She has Fibromyalgia ) So he gives her the drug that is in Robitussin for pain on its own.
