Itching or irritation in your anal region
The swollen veins at the end of the gastrointestinal tract often cause hemorrhoids. When internal hemorrhoid displaces, it triggers mucus production, which can irritate [2] the sensitive skin covering the anus. The contact of the mucus with the skin triggers itchiness, and when you act on the desire to itch, it only worsens the irritation and discomfort.
The swollen veins that cause piles may give a burning or itching sensation.
Swelling around your anus
Frequent itching caused by irritation of the anus may worsen the condition, causing the skin to get inflamed. Internal hemorrhoids can’t be seen from outside, but external and prolapsed hemorrhoids are physically noticeable as lumps or bumps on the sensitive skin around the anus. Swelling or inflammation [3] is a common symptom for all types of piles, internal or external.
The first symptom of this condition is the swelling of the veins inside the rectum, which may also cause swelling outside the anus.
