What happens if you diphenhydramine cream with diphenhydramine pills?

I have no idea, but I have 10 mosquito bites on one foot, including several on the bottom of my foot. They freaking itch and burn so bad that I cant stand it any longer. I already have diphenhydramine cream on them, and I'm getting ready to take diphenhydramine pills. For the love of god, I can't take this freaking burning itching for one more second!
