Have you by any chance tried hydrocortisone enemas or mesacol foam enemas. They are quite helpful. Let them stay in your rectum for quite some time or as long as you can tolerate. They are very helpful in cases where lower portion is more affected as in those areas, oral medications do not help.
Try some alternate cures too.
