Tightness and Nerve damage after FUE HT?

Its been 7 months now I had my FUE done. (3000 grafts) I still feel some tightness in my recipient area (crown) and it stays 24/7 without any pain, but when I'm asleep and I woke up in between I feel normal. Also, when I touch my temples, there is a slight sensation or something I feel that runs from my temple till crown area. Is this because of nerve damage? Thanks in advance.
