Why do you have a burning sensation in your fingers when you bend them?

A burning sensation in your fingers when bending them can result from various causes, including nerve compression, poor circulation, or repetitive strain injuries. Conditions like carpal tunnel syndrome or peripheral neuropathy can lead to nerve irritation, causing discomfort during movement. Additionally, inflammation or injury to the joints or tendons may also contribute to this sensation. If the symptoms persist, it's advisable to consult a healthcare professional for proper diagnosis and treatment.
