I had a cyst on my shoulder for fifteen years.. just a hard knot.. three weeks ago it burst..leaked thick puss like fluid.. now leaking blood..i ?

Sebaceous cyst: This sounds like a sebaceous cyst that is now draining. The blood is actually serosanguinous - what your body puts into hollow spaces to fill the void. If it does not stop draining on its own please go get seen.
