Looking for hemorrhoid / rectal specialist or help

Good day,
My husband is dealing with reoccurring internal, external and marginal hemorrhoids for the last 2 years. The hemorrhoids do not / have never cause any bleeding and are around stage 2-3. He is on a high fiber diet and no long has issues going to the bathroom, but his hemorrhoids continue to reoccur. He is also dealing with strange rectal inflammation / bulging that was told was not rectal prolapse that happens in the evening and is not related to going to the bathroom. He has been to numerous colorectal doctors and other doctors that are generally very dismissive or told ‘I don’t know.’ He is also experiencing constant rectal and pelvic pain and discomfort that does not relent and gets worse when lying down. He has been going to pelvic floor therapy for over a year with little improvement. Also, trying to rule out pelvic nerve issues, pelvic congestion syndrome and IBD but every test is inconclusive. Colorectal won’t preform surgery because they don’t think the pain / discomfort is from hemorrhoids, but don’t have any other suggestions. At this point we don’t know what to do anymore or what to try next. I’m trying to find a colorectal who specializes in abnormal rectal issues or who is also proficient with pelvic floor dysfunction on Long Island or NYC, but I can’t find anyone specific. Any help would be appreciated, thank you and happy holidays
