Internal hemorrhoids prolapse with pain and swelling. This is often due to inflammatory edema or thrombosis caused by the prolapse, which leads to pain and swelling. At this time, you can choose to apply lidocaine gel externally or apply golden ointment externally for anti-swelling and analgesic effects. You can also choose to insert sodium diclofenac suppositories into the anus, which has anti-inflammatory and analgesic effects, and take diosmin tablets orally to relieve anal swelling, as well as use anal cleansers or potassium permanganate solution for sitz baths to eliminate local bacteria and secretions, and reduce local infectious inflammation. After using the medication, it is still recommended to go to the hospital's proctology department as soon as possible for treatments like internal hemorrhoid banding, PPH, or TST, because the swelling of prolapsed internal hemorrhoids indicates a severe condition, and mere medication alone cannot achieve effective treatment outcomes.
