Depends on what the muscle and joint pain are from...I have continual and constant pain in both muscles and joints (think 99yr old woman rising from a seated position!)...but it sort of goes away the more I move. If I walk a long time or intensely then it is almost gone...that generally means inflammation.
Inflammation likes activity. It likes movement (think greasing the wheels)...the more you walk the more blood flows through the joints and liberates them...when you stop for long periods of time and sit or lay down, they sort of stiffen up.
If it is something else...arthritis or something similar then it may be different.
I also use a chiropractor weekly, a PT 2xs/week (I have had 2 nasty falls in 2yrs) so that things are where they belong and move better.
I hate drugs with a passion (personal opinion and experience with loved ones) so I am prejudiced against taking most of them but I did take massive doses of NSAIDs for inflammation (I would have never been able to go to work or get out of bed otherwise) and certain prescription pain meds like Tramadol (which does almost nothing for me except disconnect me from the pain (doesn't stop it) and make me drowsy).
You need to find out what the pain is (autoimmune or something else) and then treat it accordingly.
