Hi, a little paraesthesia
is expected around an incision in the post operative period, and can also be experienced if the limb is edematous or swollen, so elevate your legs and wiggle your toes. But persistent tingling appearing 2 weeks after surgery may point to cast related problems. Is the leg swollen too much, does the cast feel tight, is there any discoloration of the toes? See your doctor if it persists.
