i have these seed-like things under my skin, they started slowly and are gradually increasing. they are really hard. sometime when i suceed in using a pin to break one, there is this puss coming out and is quite dry initially then gets into a more liquid form with time, also i some times find hair in it, as if it was growing under the skin. the amount of puss that comes out of one is really surprising, it is like it has a source, and if i leave it for like 5min and press again even more comes out. one thing ive noticed is that they are quite symmetric , if i find one on my left hand, am likely to find one on the other hand. my elder sister has some too, just that hers are fewer and she claims she saw them on one of my grandmothers. please i need help
