What Causes Soreness And Purple Discoloration In Anus?

25/f. In the last two weeks I have become increasingly aware that it would seem my anus is turning purple. It started with one small spot (about the size of a pea, mind you it was a spot and not a lump). It looked like a very small bruise. After this was brought to my attention by my partner I began to pay closer attention. Now almost 2 weeks later and almost the entire anus is purple! The anus itself has always been lumpy looking but I have not noticed any out of the ordinary lumpiness. No problems passing stool (although I am not a daily go-er, usually every other day), no pain, no bleeding, and no server itching (maybe once or twice a day). I ve read plenty about hemorrhoids but I don t feel that my symptoms match up to their description other than the discoloration. Is it still possible that this purple overtaking of my anus could be a form of hemorrhoids? If not, What else could it be??
