So the other day we had that one cyst that inflated and we had the cortisone shot the next day. The cyst went down, but it was still raised and angry. Today my son was reading in class and was leaning on his hand. The cyst ruptured and there was black blood all over the place. He said his entire hand was cupped holding all the blood so it wouldn't spill everywhere.
It was scary and it hurt, but it actually looks better now. It is slightly discolored, sort of a greenish bruise color, but it isn't purple. Here is a photo of the cyst after the rupture and earlier in the week when it inflated.
