I know exactly how it hurts. Dumb me used my finger to push the head of the iron down. Anything passed the handle is hot!
Here's a great tip. Next time you are at the Dr. ask for a prescription for Silvadene. It's for burns only. It's burn cream that really really works. It's a must if you have kids and for any kitchen burns. Excellent for sunburn, stops the pain fast. I get it in the big jar and keep it in the fridge. It stays good for several years. It has been a blessing to me many times.
