If not, or if you're pregnant, your tub will suffice. Simply sit in enough comfortably warm water to cover the hemorrhoids. Gently but thoroughly clean the affected area. When you've healed enough to wipe, use unscented, white toilet tissue, which causes less irritation than colored, scented brands. You can also use Tucks or other medicated pads instead of regular toilet tissue.
Some women find comfort with an ice pack, while others swear by the heating pad and sitz bath.
Alternate hot and cold treatments to find which brings you the most relief. Ask your doctor to recommend safe topical anesthetics or medicated suppositories. There are many hemorrhoid-relief products and creams for anal fissures on the market, but consult your doctor before trying one on your own. You can also ask your midwife or doctor for a stool softener. If your own preventive and relief efforts don't stop the bleeding, then consult your medical care provider.
