Kathy, I will repeat this, when you have that numbness and tingling, it's because your nerve is being pinched in that tendon sheath in your wrist. If you wait too long, the nerve damage from being pinched will be permanent. If you get it repaired by the best hand surgeon in your area fairly quickly, the nerve may be okay.
Pat in Rockport, TX who had the same problem, but got it fixed in time, thank goodness.
