What Could Be Causing My Hands to Feel Hot and Tight?

When your hands feel hot and tight, a possible reason is that the nerves in your limbs might not be working as they should. This condition, known as erythromelalgia, causes the small nerves to send signals that loosen the blood vessels in your hands. When these vessels open up more than usual, extra blood goes into your hands, making them feel hot. Along with the heat, you might also feel a tight or burning sensation. Research suggests that this type of nerve dysfunction can lead to discomfort without an obvious injury or infection. Another condition, Raynaud’s phenomenon, usually causes cold and blue fingers, but sometimes changes in blood flow from various issues can also cause a mix of sensations including warmth. If these feelings of heat and tightness in your hands persist or cause discomfort, it would be good to talk with a healthcare provider who can look at your nerve and blood vessel function. They can help figure out if treatments to calm the nerve signals might help you feel more comfortable.
