[header] How to use tucks pads for hemorrhoids [title] Prepare a bath. [step] Before you use a tucks ®️ pad, you will need to ensure that the anal area is clean. The best way to clean the anal area is to take a warm sitz bath. <sep> (A) Allow yourself enough time in the bath to relax. [substeps] The recommended bath time should be a month for most hemorrhoids, although some states may require more for even larger ones. (B) This will warm up the area and get the colon and rectum warm to the touch. [substeps] You should also have a thermometer handy when you bathe your hemorrhoids to help determine how long they will last. (C) Sitz baths only require a few inches of water to soak the anus but you can take a full bath if you prefer. If you prefer the traditional sitz bath, just fill the tub with a few inches of water. (D) In a sitz bath, place a soft towel around the area and prop the pad in the water with a few drops of lemon or mint oil. Put the pad in the bath as the water goes on, which slowly relaxes it.
