It's not typical to have severe symptoms after surgery, I'd suggest consulting with your surgeon.
Fat Transfer Concerns
Sorry you are having this problem. Chances are the issues you are describing are secondary to temporary neuropraxia, or nerve irritation that will resolve with time. As a precaution, I would check with your surgeon. Good luck!
Fat injection and nerve sensation
It certainly sounds reasonable that the fat injection may have irritated the muscle or sensory nerves in the area. It often gets better with time. If concerned, it is always best to see your surgeon. Best of luck.
