Numbness in the middle finger: First, symptomatic treatment should be carried out. Oral nerve-nourishing drugs, such as methylcobalamin tablets, vitamin B1 and B6 tablets, and if accompanied by pain, oral pain-relieving drugs, such as aminoglutethimide tablets, meloxicam and celecoxib, as well as oral Chinese medicines, such as root pain pellets, should be taken. Second, to identify the cause, middle finger numbness is often caused by cervical spondylosis or peripheral nerve entrapment, the uncommon cause is head tumor. If it is due to peripheral nerve entrapment, the site of the entrapment should be identified and relevant electromyography examination should be performed. If the numbness is not relieved for a long time, go in for surgery to release the entrapped nerve. If the numbness is caused by cervical spondylosis, cervical spine traction can be performed, and physical therapy of the neck can be carried out at the same time. If the numbness is caused by head tumor, nuclear magnetic examination should be performed to confirm the diagnosis and then consider whether to perform surgery according to the condition.
