Does anyone get random bumps under the arm? So a few weeks ago, I had this bump under my right arm after my period. It hurt extremely bad, I couldn't even lift my arm. At first my mom said it was probably an ingrown hair, but that wasn't the case. She then told me to squeeze it and I did and it just had puss and I was like ok, just a random infection and sometimes you get them during your period. Now I have another one under my left arm. It's only been 16 days since my last period and I was wondering if its the same thing. It hurts when I put some pressure on it, but if I don't think about it, then I forget its there. I haven't told my mom about this one considering it might be the same thing, but is it?

Does anyone else get these and if so, can you help to decide what it is??

Thanks in advanced.
