Started menstruating cylce, went surfing for 3 1/2 hours and woke up the next morning with sever burning and pain under right arm
, along back side and under
. Next day spread to left armpit, under arm
as well. But no swelling or lumps, just burning pain to the touch. Its been 5 days, burning is more less intense, but still localized to my left and right armpits and pectorals.
Please help, can't find any info on why?
