How long does it take for ulnar nerve palsy to get well depends on the nerve damage, so it is impossible to give a definite answer, usually it takes 1~3 months, and some of them can’t return to normal completely. If the ulnar nerve injury is mild and the cause of the injury is removed in time, it is usually not serious and can gradually recover in about 1 month after active treatment. In this case, healthcare professionals may use neurotrophic drugs such as adenosylcobalamin and methylcobalamin to promote the growth and recovery of the nerve. Secondly, if the ulnar nerve injury is more serious and has caused contusion or rupture, some of them may recover in 1~3 months through active treatment. Some of them may not be able to recover completely, leaving numbness on the ulnar side, interosseous muscle atrophy and other symptoms. In summary, the recovery time of ulnar nerve palsy is related to many factors. For example, the severity of the disease, treatment methods, nursing care, physical fitness and so on, so it is impossible to accurately predict. It is recommended to seek medical treatment in time so as not to affect the recovery of the condition.
