This sounds so odd i think but for a couple of months now ive been having intense burning sensations under both my arm pits. Usually at night they burn like crazy and it can keep me awake. It first started with how i can only describe as an odd sensation i cant describe it and i googled odd sensation under arm pits and it said it can be a red flag for something bigger. Now its usually an intense burn. They arent itchy and i dont sweat too much. Nothing to see under my arms, no redness, no lumps etc. Dont suppose anyone has any ideas what this odd burning and feeling could be? Thankyou.
