I have a puss filled bump on my back and i assumed it was a zit and poped it but what came out was a white and clear stringy puss. Now it is crusty because the puss dried crusty and i took that off until nothing else came out. I am concerned it is a spider bite from a brown recluse.
Hi, This may be an infected sebaceous cyst. I suggest you need to have it examined by a doctor to make sure of the diagnosis. Therefore, see your doctor as you any need antibiotics.  Chat Doctor.
