What Causes Severe Pain And Numbness In Joints?

I am only 31; all of my joints creek and when I work jobs that require physical labor, the joint stressed will become hard to move, numb, and send shooting pains. I have tried a ciropractor and physical therapy for my carpotunel, yet the only thing that seems to work is not doing a repetitive motuon. There are problems with that though; I am only 31 and can t steadily hold the weight of milk. Plus when I stay still for even moments my limbs fall asleep. I do not know what a day with out pain would feel like anymore. No period in a year... had blood work recently and nothing came up abnormal. Is it normal to hurt constantly?
