See a physician: It is important to know why you are having these problem and whether it the result of a local problem, such as an injury or a systemic cause. Also, symptoms and other local signs are also important. See your physician for evaluation and appropriate referral.

Need to be evaluated: Let you doctor know. You need an neurological evaluation along with blood work to see what is causing the "neuropathic" pain. This pain may be caused by a lot of things, including, infection, medications, underlying disease, or poor diet. It could also be caused by a nerve injury. So a through evaluation is needed.

Have it evaluated.: Pain could be due to trauma (fracture, tendon or ligamentous tear, arthritis), infection, inflammation, metabolic conditions (gout) musculoskeletal (bony over growth) or biomechanical abnormality, or neurologic conditions (neuropathy). A thorough history and physical exam and possibly laboratory and radiology exams could determine the cause. Have it evaluated by a professional.
