Which is correct?

The medical term and spelling is Hemorrhoid.

The most common misspelling is to spell it like it sounds, therefore: Hemroid

Here’s what I found on dictionary.com

<—- excerpt—->
hem·or·rhoid
[hem-uh-roid, hem-roid]
–noun
Usually, hemorrhoids.
Pathology. an abnormally enlarged vein mainly due to a persistent increase in venous pressure, occurring inside the anal sphincter of the rectum and beneath the mucous membrane
(internal hemorrhoid) or outside the anal sphincter and beneath the surface of the anal skin (external hemorrhoid).
Also called pile.

(now you know!)

Here’s some other spellings I came across on various forums and blog posts.

Hemorhoid, Hemaroid, Hemmorrhoid, Hemroyd, Hemerroid, Hemmorrhoid, Hemhroid.

It really doesn’t matter how you spell it, it’s still a pain in the ass! (pun: sorry!)

According to the Venapro official website their formula administers a highly diluted mixture of ingredients all aimed at various aspects of the hemorrhoid issue. It contains a proprietary mix of many different natural herbs.  For example, the ingredient “Aesculus hippocastanum”  (otherwise know as horse chestnut) has been reported to aid in curing anal and rectal pain and swelling.

Venapro can be taken as an oral spray or as a pill like supplement, depending on the persons preference. Some people put the oral spray into a glass of water, stir and then drink it.
