I saw a surgeon today about a problem with my wrist (thankfully, no surgery needed). He told me something interesting, though, that might help you see your current situation. He said that the body builds scar tissue in the first 2 months following surgery or injury and then slowly removes the scar tissue during the 3rd and 4th month. He said the inflammation from the building of scar tissue is one of the reasons an injury continues to hurt during those first few months and why pain begins to go down and mobility begins to go up after the first couple of months. It's hard, but be patient and wait for things to improve over the next few weeks. You can't compare 8 weeks out to just before surgery. You can compare where you are now compared to a month ago. That's where you should see improvement at this point. Comparison to pre-surgery will take a bit more time. You did this surgery for the future benefits, which aren't necessarily immediate benefits.
