I've done several times before on the back of my hand to prove people wrong
And all I've ever gotten is some minor swelling redness and irritation at being touched
This time though did it to prove a friend wrong but the ysadi on the inside of my upper for arm its about an inch and a hlf from the elbow joint
Normaly it wouldn't worry me but
The fact that the entire left side of my forearm is numb and tingly even though its been 24 hours worries me slightly
As far as treatment
Warm it in wrm water for 30 or so min
Then keep it wrapped and warm
And depending on how bad it is you may need medical attentionbut I'm no expert on frost bite so I couldn't tell you how bad it is
Btw this is a picture of my arm
