He probably put a shot of cortizone in it. They have a set schedule that they give the shot on, but it does cause other problems, so they don't do it all of the time. I would do the test to be sure that you are not getting permanent nerve damage. I waited too long and a year after surgery I am still waiting to see if all of the feeling comes back in my fingers. I still can't do any type of hand sewing. So, it really depends on how bad it is. I had to have the open surger and so it took a long to heal completely and I had a lot of pain with it. Surgery is easier if you don't live alone. I had to come up with different ways of doing things because I live alone.
There are a lot of choices, just don't wait too long to decide like I did.
