My mother is having burning sensation in her left hand she is a diabetic patient and having asthma problem please help me what does it mean?

Nerve: Diabetics acquire nerve problems rather frequently, and your mother may have carpal tunnel syndrome or perhaps a tardy ulnar palsy. The asthma is most likely a co-morbidity. Her doctor can help with both.

Possible neuropathy: Neuropathy can happen as a result of trauma, or nerve damage due to the consumption of alcohol or certain medications. Symptoms can range from a numbness and tingling sensation, possibly a burning sensation, to an uncomfortable painful sensation of the extremities. Get evaluated by a professional to determine the exact cause in order to get the appropriate treatment.
