I have a small pea sized and shaped ball on my arm that both over and under the skin it feels like a ball of scar tissue its almost always pinkish I've tried popping j tr even tried sticking a middle in it and cutting it to get out whatever is in there but it's tough it's so tough I can't get a needle through or in it its extreamly hard to cut but when I was able to it barely bled its wont bo away it's kind of annoying
