I suffered from pain like that a couple of years ago - in the upper body mostly - plus foot pain as well.  Turned out surgery on one foot resolved the foot problem and an antidepressant in the morning resolved the muscle pain  - for the most part.  Since then I've learned that several family members suffer from pain all over and have been diagnosed with fibromyalgia.  I'm wondering if I have it but until the pain returns don't plan to bring it up with my doctor.  But since you are now suffering from this pain, I do suggest that you do bring it up with your doctor now.  I surely remember how scared I was at the onset of all that pain so I encourage you to maybe make a list of where you hurt and take it to him/her.  If he/she can't help, perhaps he/she could refer you to a specialist.  I now wish I had been more aggressive in my pain management, as chronic pain surely wears me down, tires out me, makes me more likely to get irritable and depressed.  So i encourage you to get this checked out pronto.  Please take care of yourself!
