Rubber band ligation is a treatment for first or second-degree internal hemorrhoids, which are hemorrhoids that are bleeding or protrude out slightly from the anus. The doctor may ligate 1 to 3 hemorrhoids, depending on how many are symptomatic.
If only one hemorrhoid is ligated appropriately, you should not feel any pain. You are likely to feel an urge to defaecate (as if you have some faeces in your rectum), which lasts for a few hours to one day. You may also encounter some bleeding for a day.
If two or three haemorrhoids are ligated at the same time, the discomfort can be quite intense. In that case, the symptoms you described are commonly seen. The reason you had difficulty passing urine is because the pain causes your pelvic floor muscle to contract. When the pelvic floor muscle is contracted, it also blocks the urethra (urinary passage from the bladder), making it difficult to pass urine.
You should speak to the doctor who performed your rubber band ligation so that he/she can see if anything can be done to help alleviate your symptoms.
