[|AI|]  Hello! Thank you for the query. What you are dealing with is most likely a colonial cyst. It's a kind of skin lesion very characteristic for the described by you area. Due to ingrown hair in this area tissues get irritated and inflammation appears. This leads to cyst formation which can be noticeable as a lump or ball. Sooner or alter such cyst gets infected what leads to pus accumulation. This gives pain and redness. I suggest you to consult a surgeon with this issue. If there is a pus, it should be incised and Chat Doctor.  After acute inflammation will be gone, the cyst should be removed. Hope this will help. Regards.
