Is the pain in the muscle, joint or nerve? Does it radiate, throb or burn???
Generally, I divide pain into categories...if it radiates down the leg from the hip or butt then it tends to be a sciatic type pain (pinched or inflamed sciatic nerve???), if it throbs often it can be a muscle and if it pulls or burns near a joint is can be inflammation or a pulled or damaged ligament...
If the hip or knee feels hot, I usually opt for inflammation.
Inflammation likes cold, or hot/cold alternating and an antiinflammatory (beware, many of us are not allowed to take them...so check with your doctor first...Even or OTC meds!)
Muscles do well with massage and movement.
My PT always told me to do the movement test...if it hurts less as you move it then it is inflammation, if it hurts more then it is damage (arthritis, ligament or joint problems)...not sure how true that is but It works for me.
