Depends on the pain
-For the chronic pain in my neck, back, and shoulders, I exercise to alleviate it, and hang upside down to release the tension. The pain is a side effect of my medication, but the benefits out weigh the costs here. Thus I learned how to cope, but I have to he diligent with the routine or the pain builds up too much.
-For temporary pain, like a muscle injury or cramps, sometimes I do nothing and sometimes I take ibuprofen.
