Medical conditions such as cellulitis or gout are known to cause hot or burning hands, according to WebMD. Additionally, the rare condition Erythromelalgia may also cause hot hands, states Merck Manuals.
Cellulitis is a bacterial infection that makes skin warm and tender, according to the Mayo Clnic. This condition can strike anywhere on the body and can potentially become life threatening. It spreads rapidly and may be accompanied by redness, swelling, pain and fever. If symptoms of cellulitis appear, Mayo Clinic recommends seeking medical help immediately.
If the warmth is concentrated around the joints, gout is a possible cause, according to WebMD. A type of arthritis, gout is usually characterized by a sudden onset of symptoms, with pain concentrated around joints such as those in the fingers. If left untreated, gout can become worse, so it is important to seek medical treatment as soon as symptoms of gout develop.
Erythromelalgia causes the arterioles of the hands and feet to expand, creating a hot or burning sensation. This feeling may last for a few minutes or for several hours. Though it can present itself at birth or during childhood, the condition typically hits people in their 20s. Symptoms are usually triggered by warm external temperatures.
