It is very difficult to tell based just on these photos. You need to be examined in person to determine this. Since you're only 4 weeks after surgery, you should consider waiting to see how things heal. You may want to get yet another opinion. Make sure you see a BC PS in your area.
I am not sure what your issue is. There may be a muscle issue but it is difficult to say for sure from the photo. At this point you have to let things heal.
