Could I have damaged grafts after 25 minutes of sun exposure? 2 weeks post-op.

I was outside midday chatting with some friends and lost track of time. I felt a tingling sensation before realizing how long I had been in the sun. Since then, I continue to feel tingling, and occasional stinging. Overall I’m not in pain. I’ve checked my head and everything looks normal to me. I can’t tell if it’s possible I damaged the grafts, or if the tingling/occasional stinging is just the nerves in my head reacting to the heat. Please note I had an FUE procedure around 15 days ago.
