Hello,
Welcome to ehealthforum and thanks for writing
Hemorrhoids are masses or clumps (cushions) of tissue within the anal canal that contain blood vessels and the surrounding, supporting tissue made up of muscle and elastic fibers. Although most people think hemorrhoids are abnormal, they are present in everyone. It is only when the hemorrhoidal cushions enlarge that hemorrhoids can cause problems and be considered abnormal or a disease.
Other possibilities could be formation of perianal hematoma, external hemarrhoid, anal ulcers, fistula,skin conditions etc. It requires a proper physical examination to comment regarding this so that accordingly treatment can be started with medication as antibiotics or antifungals. Kindly visit a Physician earliest for evaluation.Consider taking Sitz bath which might help in relieving the symptoms.
Take care!
