Awww, bless you. I'm not medically trained but twice in my life I've had boils under my arms. They are extremely painful and fill with pus like you say. I was barely able to rest my arms by my side when they were at their worst. It happened both times when I was run down, the first time after the birth of my first baby.

Chrissie is right. You need to see a doctor who will confirm what they are and antibiotics will be needed to clear them up..

You're obviously worried to ask for help on here but please ring your GP and get the help you need to clear it up.You don't need to suffer in silence
