Foot Concerns

I have been doing my stretching exercises a couple of times a day and I realize that I have only been to one physical therapy session but I have some concerns about the status of my foot. Before I started doing my stretching exercises, my foot felt a whole lot better than it did before the surgery. Now that I have started the exercises and physical therapy, I have started to have pain in the same area as where it was prior to the surgery. I am hoping that this is residual pain from the surgery but it feels almost exactly like it did prior to the surgery but just on a little lower level. I plan on giving it some time and then, if it does not get any better, I will go in for a second opinion as to what is going on and what can be done at this point.
