[|AI|]  After surgery, there are a few problems that are common. Quite commonly, an abnormally fast heart rhythm known as atrial fibrillation may occur. Your doctor may already be aware of this and have him on appropriate medication but let the doctor know of the 132 heart rate just to be sure. Hand numbness may occur after surgery due to changes in nerve function with medication and fluid shifts. If this does not disappear after 2-3 weeks testing should be done to be sure of the source of symptoms. Often, all that is needed is a protective hand brace worn for a few weeks to achieve recovery.
