I would like to ask if this is a hemorrhoid? Is it serious? Do you need surgery?

The first affiliated hospital of Henan College of Traditional Chinese Medicine anorectal disease treatment center Zhang Shuangxi: may be inflammatory external hemorrhoids or thrombosed external hemorrhoids. You can take appropriate anti-inflammatory drugs like levofloxacin, and use external washing with mannitol water and topical application of Ruyi Jinhuang cream. Usually the pain can gradually improve. However, if you want to completely remove the exposed swelling to avoid recurrence, the only treatment is surgery. The first affiliated hospital of Henan College of Traditional Chinese Medicine, the anorectal disease treatment center Zhang Shuangxi Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): Yesterday, the anal pain began, the outside of the flesh exposed can not retract itself, a little edema, contraction of the anus pain. I went to the clinic and said it was an external hemorrhoid. I’ve never had it before, but do I need to be hospitalized for surgery in this case?
