Hey there! I had a similar experience after my FUT procedure. The tightness and numbness are totally normal side effects that many people go through. In my case, it lasted for about 2-3 weeks post-surgery before gradually subsiding.
I found that gentle massaging of the scalp helped alleviate some of the tightness, and following my doctor's post-op care instructions closely really made a difference. If you're concerned though, always best to reach out to your surgeon just to be safe. Overall, while it can be uncomfortable, the end results are definitely worth it in the long run!
