Ingrown Hairs On Groin, Itchy, Blood And Pus Discharge, Lumps, Painful To Touch. Cyst Or Bruiseor?

So ive been dealing with a llot of intense itchy irritation and ingrown hairs on my groin and inner thighs. Recently, theres been a lot of pus/blood discharges from some of the worse ingrowns. Recently, theres been a large lump on one of my inner thighs, im not sure if its a cyst or a bruiseor what, but it is painful to the touch, and deep enough under the skin, that squeezing it to achieve a pressure release is a futile effort. Is that even something that would help? I do a lot of walking/running, and i do tend to sweat heavily in those regions. How do i cure this, and how can i prevent it from happening again in the future?
