Ok so i had this pus filled cyst thing under my arm in my arm pit region. I lanced it with medical scisors that belonged to my older sister and pus and blood litteraly shot across the room. Like a meter and a half. I had to clean it off the wall..... It was really hard before but now its not as hard and most of the fluid and pus is out of it. I had to cut about a quarter centi meter to reach it then ti was circular and about 2 centi meters in diameter. But that not what im worried about the pulse in the arm that has the cyst is not much weaker and the whole arm feel a little numb and weak. This could be due to the fact that i had that arm raised above my head for about half an hour but i dont know for sure. The pus was pale yellow in color also clear fulid came out, the blood that came out was very thin. I think i covered everythin but i dont know for sure please tell me what you think.
