Yes, haemorrhoids can cause a feeling of anal swelling and swelling, which is a common cause of anal swelling.
Haemorrhoids that cause anal swelling are usually internal haemorrhoids, and patients may also have other symptoms such as intermittent post-poo blood dripping and the nucleus of the haemorrhoid prolapsing outside the anus during defecation, which require a visit to the hospital for examination and diagnosis and identification by a specialist doctor.
