The numbness is also not uncommon. Sometimes it depends on what type of surgery was performed. During the surgery, the tissues may become swollen and inflamed. Also, sometimes the nerves get stretched out in order to reach the bone or to get inside the joint. Nerves are very delicate structures. If they get stretched, swollen, or compressed during the surgery, it may take 4-8 (or even 12-16) weeks for the nerves to return to baseline. Rarely, some numbness remains forever. This can occur when the nerves of the skin are cut when an incision is made. There is no way to avoid that.
I encourage the usage of vitamin B complex vitamins for those suffering from nerve-related pain after surgery.
I hope this helps. Stay optimistic, positive, and motivated. Listen to your doctor and therapist, and work hard to get the best outcome possible after the surgical treatment you received.
