Why is my left hand burning? i notice this when i was in the shower. my left hand felt like it was in boiling water. i had hurt it about 2 weeks ago.

Nerve injury: Depending on the location of injury, it could be some damage of nerve origin. Nerve pain is frequently described as burning type of pain. Did you fall on your left arm/elbow/shoulder? Ifso, try Ibuprofen 600 mg for one dose with food (unless you have stomach issues). If there is inflammation that is causing pressure on a nerve, it should alleviate. I would strongly recommend seeing a doctor.
