Guidance

I have a question & hoping someone can tell me what type of doctor I need to see...I have had perianal abscess (5) in the last two years that develope & are painful. I have had them cut & drained & some I have let it rupture on their own (too painful to get cut & drained for me).

After having one cut & drained a week ago again, I asked by PCP to refer me to a GI doctor to see if we can find out why I keep getting them. The GI office called & stated that they don't see people for that & nothing they could do for me.

I'm fine if I just happen to be one who will get them for no apparent reason, not going to over anaylze it, but I guess if a GI is not one who could try too find out why I get them, then who?
