those are PAINFULL! I would apply warm compresses to help it come to a head faster and when it does, do not squeeze as that can damage the tissues around it and actually push bacteria deeper into it. Open it gently, from the side, with a sharp sterilized needle. A sewing needle is generally sharper than a stick pin. Once it is open, then squeeze very gently from as far around it as you can, wiping away any and all pus with a clean cloth, tissue, etc. Then take a nice long hot bath, washing gently. After your bath, apply some bacitracin or other antibiotic cream and cover with a bandage. You may need to open again in a day or so to empty it again but always apply warm moist compresses at least a couple of times a day. What that does is increase blood flow to the inflamed area and speed healing as the white cells in your blood does its job.
