How come my body is in so much pain.. all the time but there are no explanations.. it makes me want to cry.

More detail: Could you go into more detail and explain the type and location of the pain?

Perhaps psychic pain: If you are having total body pain that has been investigated, and no cause was found, then it is possible that the pain starts in the central nervous sytem causing psychic or psychologically-induced pain. Pain is a subjective symptom and us physicians and scientists doofus not have--as yet--a good way to measure pain severity. If physical causes have brent ruled out, pursue possible psychological.
