I have had this hard lump a bit smaller than a pee under the skin of my penis for 2 months, it is on the left underneath side and is on the borderline of where the hair is growing, it doesnt hurt and it doesnt grow a white head or anything and sometimes gets a little red, when i squeeze it occasionally a little bit of pus comes out and the lump seems to get a little bit smaller, i dont know whether its a blocked/infected hair follicle or lymphocele, what can and should i do about this
