I'm not an expert, so please ask your doctor first if you want to try this.
Last time I had external hemorrhoids, I used a corticosteroid ointment and had a horrible allergic reaction. My hemorrhoid itched and hurt more after using the ointment then before! I guess I'm allergic to corticosteroid.
Since I couldn't use the ointment, my hemorrhoid got worse in the following couple of days. It was very painful and I couldn't even sit on it. I searched my medicine cabinet for something that would help and found a topical aloe vera gel ointment with lidocaine for cuts and bug bites.
I wasn't sure if this would be safe or not but I was willing to risk it so I applied it on the hemorrhoid. Within five minutes, the pain and itch literally disappeared! I applied the gel several more times for the next two days when the pain came back and it healed my hemorrhoid completely!
I think aloe vera gel has healing properties and of course the lidocaine eased the pain. This is the best hemorrhoid treatment I've ever tried.
