One Blurtit User Stated:
"I noticed when I put my hand down it hurt on my knuckle by the pinkie. Upon looking at it, I noticed a red circle about the size of a dime and a raised blister in the center. My pinkie actually feels rigid rather sore to bend. And the blister hurts to touch. There is no itching."
And Another, A Self-Confessed 'Medical Assistant':
"If you notice any type of redness, pimples, or swelling you can try Benadryl. If it is really painful and you get a fever etc., you may want to see a doctor. Good luck and take care."
