Hello, Earlier today I was cooking. The oven was at 500 degrees F, and I went to pull the oven grate out without thinking. I grabbed it with my left hand and heard it sizzle, immediately pulled my hand out and ran it under cool water for about 15 minutes. I then put some aloe vera on my fingers and wrapped them in band aids. I now have blisters on 4 of my fingers, and the blistered areas are numb. Is this normal? Should I see a doctor or will the feeling come back? Thank you, Marissa
