First, you'll want to treat the constipation. Can you target what it is you're eating that might cause constipation? Do you eat 5 fruits or vegetables a day? IT's important to have a soft stool. Otherwise, hemorrhoids DO occur.
Hemorrhoids are swollen, inflamed veins around the anus or lower rectum and are often the result of straining to have a bowel movement. The most common symptom of hemorrhoids inside the anus is bright red blood covering the stool, on toilet paper or in the toilet bowl. Symptoms usually go away within a few days. Treatment may include warm baths and a cream or other medicine. If you have large hemorrhoids, you may need surgery and other treatments.
If you are experiencing regular rectal bleeding you should see a doctor. You need to make sure bleeding is not from a more serious condition such as colorectal or anal cancer.
To soothe itchy skin, you can try cold compresses, lotions and lukewarm baths. Avoid scratching, wearing irritating fabrics and high heat and humidity. Most itching is not serious.
