Forehead Indentation after wearing hat 4 weeks post brow lift. Any suggestions? (photos)

I am 4 wks post lower FL, upper bleph, and endo brow lift. Yesterday, I was working outside for several hours wearing a big SPF 50 hat. It was hot. After taking off my hat, I had an indentation from the brim. It was still there last night after 5-6 hrs, and I thought it was swelling from the heat, and it would be gone this AM. It is not. It is slightly better, but you can still see an indent. Did I mess something up, or is this just swelling? My entire face seems more swollen today.
