Throbbing at day 17. Is it normal? (Photo)

Hi i did the FUE 17 days ago,2000 grafts.No side effects,almost no headache,crusts have almost fallen,but today I felt strange by the time i woke up. It's like touching slightly my scalp with a knife,throbbing.Not all the time and not at a specific part.It's mostly at the transplanted area but I feel it at the donor area too.It's not too disturbing but I am worried. Also my skin at the transplanted area seems very sensitive and it's like still having anaesthesia at it.Is that normal at day 17?
