Question about hemorrhoids - Where do they occur? How do they look visually?

My question is just where in the anal area do hemorrhoids occur? Do they just occur on either side of the midline or can they occur anywhere around the anal opening? I have a small purple hard 'marble-like' painful place at my anal opening but it is toward the back and I'm just wondering if it would be a hemorrhoid. I have a dr.'s appt scheduled but looking for advice until then.

Hemorrhoids are varicose (swollen or dilated) veins located inside the anus (internal hemorrhoids) or around the exterior of anus (external hemorrhoids).

External hemorrhoids are varicose veins located on the outside of the anus, under the skin. They are more frequently associated with painful irritation, especially when a blood clot forms within the dilated vein.

Most cases of hemorrhoids can be treated at home. On rare occasions, surgery is required to remove hemorrhoids.

Hemorrhoids symptoms are:

Pain and pressure in the anal canal.
A grapelike lump on the anus.
Itching and soreness in and around the anus.
Blood on underwear, toilet paper, the surface of the stool or in the toilet bowl.
Symptoms can be made worse by straining during constipation and overly aggressive wiping of the anus

To reduce pain and itching of hemorrhoids, you can try these methods:

Take sitz baths; sit in a shallow bath of warm water several times a day. Don't add anything to the water.

Use a hemorrhoid cream (like Preparation H) or suppository. Follow the directions on the package. These products help with the symptoms, but they don't shrink the hemorrhoids.

Don't strain during bowel movements. Talk to your doctor about using a stool softener to help with constipation.

Avoid becoming dehydrated.

You can prevent hemorrhoids by keeping bowel movements regular and stool soft. Also, avoid prolonged standing, sitting, and heavy lifting, and chronic coughing, straining at stool, and aggressive wiping.

Hemorrhoids can occur anywhere around the anal opening - this are external hemorrhoids. Internal hemorrhoids develop deeper in the rectum above the dentate line.

It is important you see a doctor to be sure what it is. Wrong treatment can only cause more damage.

In case your doctor will confirm that it is a hemorrhoid I suggest you try Rue Care Oil. This oil truly delivers amazing results - it shrinks the hemorrhoid, stops bleeding if there is any, repair the damaged tissue, strengthen the veins and so prevent hemorrhoids from returning.
