Hello, I had a FUE transplant 8 days ago. Today I was wearing a loosely fitting baseball cap. A friend came to me, unaware of my transplant, and tapped me firmly and also rubbed my head (still wearing cap). I immediately made him aware of the situation. Anyway, I check the area about 10 minutes late, no sign of blood, just a slight tingle on my scalp. I am now worried that he may of dislodged or damaged the crafts. Any thoughts? Thank you.
