The minor procedure: Excision under local anesthesia<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">In cases of severe, fresh pain, a brief procedure brings the fastest relief.

Anal thrombosis can also occur during and shortly after childbirth due to straining.  <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The good news: Even in pregnancy, anal thrombosis is harmless and usually regresses on its own. The focus is on gentle, conservative measures \u2013 cooling, stool regulation, sitz baths, and pressure-relieving sitting. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Which ointments or painkillers are suitable should always be medically coordinated during pregnancy. A surgical procedure is only rarely necessary and only in cases of very severe symptoms. <\/span><\/p>\n<h2><\/h2>\n<h2><b>Prevention: How to lower your risk \u2013 especially in summer<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Drink enough fluids<\/b><span style=\"font-weight: 400;\"> \u2013 keeps the stool soft and prevents hard straining.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Eat a high-fiber diet<\/b><span style=\"font-weight: 400;\"> \u2013 vegetables, fruit, whole grains, psyllium or flaxseeds if necessary.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Interrupt prolonged sitting<\/b><span style=\"font-weight: 400;\"> \u2013 take breaks on vacation trips, stand up during flights.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Avoid heavy straining<\/b><span style=\"font-weight: 400;\"> \u2013 an elevated foot position on a stool improves posture during bowel movements and facilitates evacuation.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Gentle anal hygiene<\/b><span style=\"font-weight: 400;\"> \u2013 soft paper, additionally water, no aggressive rubbing.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Moderation with alcohol and spicy foods<\/b><span style=\"font-weight: 400;\"> \u2013 especially on hot days.<\/span><\/li>\n<\/ul>\n<h2><\/h2>\n<h2><b>Frequently asked questions (FAQ)<\/b><\/h2>\n<h3><b>Is an anal thrombosis dangerous?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">No. It is very painful but harmless. Since it is located in superficial veins under intact skin, it cannot detach and cause a pulmonary embolism \u2013 an important difference from deep vein thrombosis.  <\/span><\/p>\n<h3><b>Does an anal thrombosis go away on its own?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, usually. The body breaks down the clot within days to weeks. However, in cases of severe pain, you do not have to endure this time \u2013 treatment accelerates relief.  <\/span><\/p>\n<h3><b>Anal thrombosis or hemorrhoids \u2013 how do I distinguish between them?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Anal thrombosis comes on suddenly, is visibly located on the outside of the anal margin, is bluish, and very painful. Hemorrhoids develop slowly, are located in the anal canal, and are often noticed due to painless, bright red bleeding. <\/span><\/p>\n<h3><b>What helps quickly against the pain?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Cooling, anti-inflammatory and analgesic ointments, sitz baths, soft stool regulation and \u2013 according to medical recommendation \u2013 painkillers such as ibuprofen. For severe, fresh symptoms, excision under local anesthesia is the fastest solution. <\/span><\/p>\n<h3><b>How long does it take to heal?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Usually one to two weeks, rarely longer. After an excision, pain relief usually occurs immediately. <\/span><\/p>\n<h3><b>Do I need to be ashamed of the doctor&#8217;s visit?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">No. Complaints at the anus are among the most common reasons for a proctological visit. We handle them professionally, discreetly, and routinely.  <\/span><\/p>\n<h2><b>Conclusion<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">A sudden, painful lump at the anus is almost always an anal thrombosis \u2013 a harmless but unpleasant blood clot in the veins at the anal margin, which is often confused with hemorrhoids.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It usually heals on its own; in cases of severe pain, a minor procedure provides rapid relief. Especially in summer, it is worth keeping an eye on the typical triggers \u2013 and having any uncertainties clarified by a specialist. <\/span><\/p>\n<h2><b>Proctology at VenaZiel in Berlin<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">In our <\/span><a href=\"https:\/\/venaziel.de\/en\/proctology\/\"><span style=\"font-weight: 400;\">Center for Proctology<\/span><\/a><span style=\"font-weight: 400;\">  at VenaZiel in Berlin (Charlottenstra\u00dfe 13, 10969 Berlin-Kreuzberg \u2013 directly at Checkpoint Charlie, between Mitte and Kreuzberg), we treat anal thromboses discreetly, gently, and according to the latest professional standards \u2013 from conservative therapy to outpatient excision under local anesthesia.
