Swelling, tingling an numbness on left side of the body only aware of pinched nerve, however swelling an constant feel of pins an needles are recent.

Tingling : Tingling and numbness that affects half of the body (which most people mean as including an upper limb, a lower limb, one side of the trunk, and sometimes one half of the face) can be caused by a problem in the brain or spinal cord. A pinched nerve can not cause those sorts of problems. Swelling of half the body is very uncommon. Such problems should be evaluated by a primary care doctor (family practice or internal medicine) who can help determine if a specialist is needed.
