Hello everyone I am 32 years old and work in an airline company.I want to share my story here with all of you.Whenever I shave I have these red rashes in my armpits.They just come and go naturally and do not require any medication but last week was different because after shaving arms armpits I had this lump in armpit which is really nasty.I am unable to move my hands properly.I am also worried as this could be cancer or could it be?
