Paraesthesia is a burning or prickling sensation that is sometimes felt in the hands, arms, legs or feet. It can also occur in other parts of the body. It can also feel like tingling or numbness, skin crawling, or itching. The feeling is not comfortable, but it is not painful. (The "pins and needles" feeling that happens when a foot or hand "falls asleep" is a temporary paraesthesia.)
Paraesthesias that last or come and go may be caused by medical issues that need to be treated. These include stroke, a bulging disk pressing on a nerve, a trapped nerve, vitamin deficiencies, uncontrolled diabetes, alcohol abuse, or even certain medicines.
Tests are often done. These tests may include blood tests, X-ray, CT (computerized tomography) scan, nerve conduction studies (NCS), or a muscle test (electromyography). Depending on the cause, treatment may include physical therapy.
Tell your healthcare provider about all medicines you take. This includes prescription and over-the-counter medicines, vitamins, and herbs. Ask if any of the medicines may be causing your problems. Don't make any changes to prescription medicines without talking to your healthcare provider first.
You may be prescribed medicines to help relieve the tingling feeling or for pain. Take all medicines as directed.
A numb hand or foot may be more prone to injury. To help protect it:
Always use oven mitts.
Test water with an unaffected hand or foot.
Use caution when trimming nails. File sharp areas.
Wear shoes that fit well to avoid pressure points, blisters, and ulcers.
Inspect your hands and feet carefully (including the soles of your feet and between your toes) daily. If you see red areas, sores, or other problems, tell your healthcare provider.
Follow up with your doctor, or as advised. You may need further testing or evaluation.
Call your healthcare provider right away if any of the following occur:
Numbness or weakness of the face, one arm, or one leg
Slurred speech, confusion, trouble speaking, walking, or seeing
Severe headache, fainting spell, dizziness, or seizure
Chest, arm, neck, or upper back pain
Loss of bladder or bowel control
Open wound with redness, swelling, or pus
