In my case, it is just plain old age trickling in... and different parts hurt every day. It is my unfounded belief that stress cause an affinity for pain, and the particular area in which pain occurs is related to sleeping habits,usual daily positions, temperatures in various rooms, dampness [not evenly distributed throughout the house], and plain ornery-ness within the body.

I gobble advil, for various reasons. Funny thing - I do not feel pain when out shopping. Of course the pocketbook feels the pain later.
