Whether hand numbness caused by carpal tunnel syndrome can be self-healing should be decided according to the severity of the symptoms and the cause of the disease. If carpal tunnel syndrome hand numbness is caused by simple tendon swelling, the symptoms are relatively mild, and there is a possibility of self-healing after the swelling subsides. If the numbness of carpal tunnel syndrome is caused by the increase of carpal tunnel contents, carpal tunnel bleeding, etc., it is generally more difficult to heal by itself, and need to be treated in a timely and professional manner. Carpal tunnel syndrome, also known as mouse hand, is a syndrome that occurs when the median nerve in the carpal tunnel is compressed. It triggers hand numbness symptoms, with the aggravation of the disease and the gradual severity of the first finger numbness can be progressed to the palm of the hand, forearms and even upper limbs numbness. If the numbness is caused by swelling of the tendon, it may gradually recover after the swelling of the tendon subsides. If the hand numbness caused by carpal tunnel syndrome is caused by bleeding in the carpal tunnel and the nerve compression is more serious, it is usually more difficult to heal on its own and needs to be treated in time according to the severity of the disease. If the symptoms are mild, the patient can be treated conservatively with low-dose lasers or prednisolone under the guidance of a physician; if the symptoms are severe, open surgery or arthroscopic surgery should be considered. If symptoms such as hand numbness occur due to carpal tunnel syndrome, you should go to the hospital in time for examination to clarify the cause of the disease and carry out targeted treatment as early as possible.
