Don't doubt yourself. It wasn't easy to get the surgery, but you did it. Now, trust in yourself & let the band do it's job.
Also, if you have too much pain call you doctor. Run it by them & see if they think you should be concern.
I didn't want to bother anyone, so I just stuck it out. Come to think about it, I should have bothered them. If I bought a car that wasn't running right, I would called the dealership. I am so much better than any car I have driven, so I should have talked to the nurse at the office at least.
Good news is I was alright! I pray you will be too!
