Sciatica/Pinched Nerve Pain
This can be caused by herniated lumbar discs, tight piriformis muscles, spinal arthritis, bone spurs, etc. The pain can radiate from the low back to the leg(s), with numbness, weakness, or tingling.
Anti-inflammatories, muscle relaxants, anticonvulsants, and antidepressant medications have all been used to treat this pain. Sometimes, epidural injections may be part of a comprehensive treatment plan in order to facilitate physical therapy and help alleviate the pain.
Vascular Leg Pain
Causes may include blocked arteries, inflammation of the arteries, circulation diseases, and more. Pain from lack of circulation can be very severe.
Surgical bypass is usually the cure for these diseases, however, there are cases when surgeries are not feasible. Pain relief may be achieved with oral medications, sympathetic blocks, and spinal cord stimulators.
Diabetic Nerve Pain
With longstanding elevated blood sugar, some of the diabetic patients may develop pain in the feet/legs. The so-called diabetic neuropathy can be very painful.
Burning, shooting, tingling pain is the usual description. A pain specialist can work with your primary care provider or endocrinologist to help you deal with this type of unrelenting pain.
