Hello: I am a 52-year old female. For some time I have had a large cyst in my groin (pubic) area. The area has become so irritated by my underwear, the skin covering the cyst-like lump has rubbed away causing extreme pain. There used to be clear liquid coming from the lump, but now it just has a raw appearance to it with no drainage. Funny, but in the morning it appears to be much smaller and less painful and it increases in size,as does the pain, as the day progresses. What could this be???
