Hi, I am 26 years old and found a lump about the size of a pea underneath my armpit. It is not painful at all and doesn t really move if I move the skin around. It is not noticeable unless I pull tight on the skin. There is no redness at all, in fact you wouldn t even know it was there unless you felt it. I cant really pinch my skin without grabbing it but it also seems as thought its attached to something on the other side of the lump as well. I could do whatever to it and it doesn t bother me a bit. Any ideas... I have had a lot of allergy problems to foods and other things that I have found out in the last few months. So my body has had some changes it has gone through recently. I have minimized the amounts of allergic dermatitis rashes I have been getting...not sure if this would have anything to do with it?? Can anyone help? Thanks
