Did your Dr not suggest a MRI or possibly a CT scan, after he realized that you were not progressing normally? ODD!
I don't have any suggestions, but I would think they would be concerned and start looking for an answer through these type's of test. When are you scheduled to go back for a checkup?
If he seems to be brushing you off, then it would alarm me, and I would start seeking out another opinion from a qualified surgeon. Have you made this known to your PCD?
It takes quite a bit of time too heal from this type of surgery, but they should know about where you should be at this time Post OPP. If their saying that it's bad then shey should also be doing some testing, unless thay are waiting for the swelling to go down first.
Please keep us informed. Good Luck!
