Pain
"I took this for a number of years for long term chronic pain. It worked WELL without making one unable to function. I was very disappointed when it was taken off the US market by FDA and have not found anything comparable since. Now I have been in level of pain that is uncomfortable all the time or be doped to where not want to do much. Darvon was linked to causing heart attacks tho my understanding is it is still used in much of the world."
