My aching bones

Is it my bones? Is it my muscles? Both? Why am I so tired? Am I too young for arthritis? What is going on? I have noticed over the past year or so, that my body hurts...a lot. It is not since I began Derby, it was long before that. I take otc Ibuprofen...doesn't help. I have been seeing a foot doc, and have a bone spur in my left foot. Explains the foot pain...but not the leg pain/ache. I am heavier than I would like to be, than I should be. I am working on that, or should I say struggling with it. However, it is difficult to exercise everyday when your body already hurts. It is really frustrating. To say the least. What to do? I hate complaining...but I am complaining...
