I have two lumps in my armpit. 1 about the size of a quarter. I squeezed it and white puss and whiteish clear liquid came out. The other is alittle bigger than a pea and I squeezed it and nothing came out, I am 19 and have been breastfeeding for almost 8 months.
Hello! Thank you for the query. The most probable reason of these lumps is hair follicle infection. Such infection is usually caused by shaving with non-sterile razors. If you use an antiperspirant in this area, this might be also a reaction for this agent. The lumps if are painful and swollen, most likely contain pus. The best treatment for it would be an incision and Chat Doctor.  I suggest you to consult general surgeon or dermatologist with this issue. Next time you will be shaving, please try to use sterile razors. Hope this will help. Regards.
