How long after my carpal tunnel surgery should my fingers regain feeling?

This is variable: Some have immediate return of sensation while some will take longer. Some will notice an improvement right away but still feel tingling and will describe this as "numb" the return of sensation is dependent on many factors including age, general health, duration of symptoms, circulation and the actual mechanical severity of compression. http://www.handctr.com/carpal-tunnel-syndrome-q-a.html.

Degree of injury: If this is severe carpal tunnel with axonal injury this could take 8 to 10 months or never completely return, if it is mild with only neuroapraxic injury to the nerve should only take weeks to return or even return immediately. Refer to your nerve conduction studies and EMG to try and get a feel for length of recovery time.

Depends: This is a common problem. It may improve with time.
