ddcc- the title caught my attention because I struggled with this from medication making me constipated.
Ice works, but if it's thrombosed (a clot formed under the skin) you have 2 choices, let it resolve on it's own or have it removed. I had one before and let it resolve and it took about 2 weeks, 4 days for the pain to go away, and the rest for it to dissolve. I had one burst and had to go the ER and then had to have one removed with surgery because it was starting to bleed and they were afraid it would burst, when can cause a lot of bleeding that won't stop. The only time I get them is while pregnant! You'll need to catch it within 3 days, or else they won't bother with surgery by then (recover is painful, but less painful than the actual hemorrhoid if you get it before the 3 days, if that makes sense) They can do the surgery while pregnant - I had it done a few weeks ago, they just can't use certain pain medication or anesthesia.
Otherwise, ice packs, use colace (or magnesium supplements) to keep the stool soft to not make it worse. Use baby wipes instead of toilet paper. Doctor also recommended putting tucks or witch hazel pads in the fridge or freezer, and using like 6 pads at a time and keeping them there all day, changing every few hours.
I also used Earth Mama Angel Baby because it was on clearance at our local store, but apparently it didn't help because I ended up in the ER a few days later
I was given a prescription cream though, so mine might have been beyond the ability of the Angel baby stuff.
