I have a knot that has came up on my scrodem by the base of my penis it appeared Monday night the size of a pea and is almost the size of a golf ball now it is painful when walking and seems to be causing everything else to swell any ideals on what this is  please help an thank you
HelloThanks for query. The painful knot on the scrotum near base of the penis is mostly a Staphylococcal infection of hair follicle in a stage of induration. You need to take broad spectrum antibiotic like Augmenting along with anti-inflammatory medication like Diclofenac twice daily for 10 days. If it does not regress with this treatment you will need to consult qualified General Surgeon for evaluation and to get it incised and Chat Doctor.
