Hello, I have a problem regarding the skin on my forearms (interior part). Since summer came, a few (3-4) bulges appeared on my forearms. They are small (2 mm diameter), almost flat, skin colour. They feel under skin when touching. They dont seem to evolve. I tryed to compel one, and it only inflated a little and got red and painfull for 2 days, and it became as innitial. I taunted the skin and compel, and only a litle blood came out, no infection or acneea-like. What is this? What should i do?? Please, answer me, thank you !
