Take a nice warm bath, do this every day. Also, TUCKS pads are a lifesaver and will help to clear it up. I had the worst hemorrhoids and constipation when this pregnancy started, I did this for a few days and things started to clear up. Hope you feel better, I know it's a pain in the ass. ;)
shred a raw potato, put it over the area & put a pad on. I had them horrible while pregnant with #1 & after delivery (tore through my rectum) and my Dr totally said it would work & it did. It is a natural anti-inflammatory. I also made suppositories out of potato by using a drinking straw to shove through it. I know it sounds nuts - believe me I do - but it worked & by the time I decided to give it a go I'd have shoved anything up there to get it to stop. I could NOTHING without serious pain. It can be absolute misery. For me - 3 days of that & I no longer had any hemorrhoids that I could tell. I also hate to be so TMI - but you need to GENTLY push your external one in if you can. :S It can't heal until it goes in.
Really. I know it sounds weird as smurf, but it really worked. It feels really weird at first but the relief is almost instantaneous. The other suggestion was to stick a clove of garlic up your ass....so I decided to try vicks lol.
