Many people quietly deal with painful skin problems and think they are the only ones. The truth is that you are not alone.
A swollen, painful lump in the armpit is far more common than most people realise, and it can make simply lifting an arm difficult.
The armpit has many sweat glands and hair follicles, and shaving, sweating and friction can all irritate them.
When a follicle or small cyst gets blocked and infected, it can grow into an abscess: red, hot, tight and full of pus.
Some people get these lumps again and again, which can be a sign of a long-term condition that a dermatologist can help manage.
