What to use to treat recurring muscle pain?

From what? Recurring muscle pain could be as benign as aches from exercise or occasionally sign of nutritional deficiency (potassium, calcium, magnesium, etc.) or something that indicates a birth defect in the body's ability to process energy releasing compounds. For minor muscle aches, heat, massage and otc analgesics are usually helpful.
Consider eval. Stretching, heat from a shower or heating pad (don't get burned), massage, & acupuncture can help. Nonsteroidal anti-inflammatory drugs (NSAIDS) can help with both pain relief and in reducing inflammation. Examples are ibuprofen (like Advil, Nuprin or Motrin), Naproxen sodium (like Aleve, (naproxen) Naprosyn, Anaprox) or Asprin (such as Bayer, Ecotrin, Ascriptin). Avoid NSAID's if pregnant or allergic.
