This is a picture of under my arm (the armpit.) The entire right side of my chest from collar bone to bottom of rib cage then along the side and halfway up into my armpit is red/burned.
The area under the arm has turned more red since last Tuesday and is quite tender and sore. I cannot stretch my arm up above my head without it hurting. (Luckily I don't have to stretch up that often.)
The area is actually redder then this picture depicts.
I walk 5-7 miles a day and am being careful not to swing my right arm too much so it won't chafe that sensitive area. The nurse gave me a tube of Aquaphor (which is basically petroleum jelly) and I have used that a few times. I don't think it makes a difference. I should think the burn will start to dissipate soon.
Needless to say I am not putting a razor anywhere near that area and I gently soap, rinse and pat dry.
