Need some advice on medications

Jazmin • Mother to an angel... I love you Adelyn Rae Bower 5.8.15
On Monday I went to the beach and like the idiot I am, I sunscreened everything but my ankles and the top of my feet and now I think I have sun poisoning. I've been putting fresh aloe on the burns for the past 2 days now but I still can't put any pressure on my feet without it feeling like I'm being stabbed by a million different needles. 
Is there any over the counter medicines that I can take for the pain other then Tylenol?
I have a doctors appointment at 3:30 with my regular physician but I was just curious if there was anything I can take beforehand for the pain.
