Had surgery for carpal tunnel release this morning my hand & fingers are still very numb & it hurts to straighten them & its been 8 hrs, is thi normal?

Contact surgeon: If you were numb before surgery it will take few months to improve. If you were not, contact the surgeon as local anesthetic should be gone by now.

Can be: At times some irritation to the nerve adds to symptoms, other times. Local or a block take longer to wear off, finally make sure the bandage is not too tight. If concerns persist call your surgeon.
