Hemorrhoids are a more common anorectal disorder. Simple internal hemorrhoids do not usually cause pain, but there may be blood in the stool. If internal hemorrhoids are painful it may be related to other lesions near the anus and further examination is needed to determine the cause and treat the cause. Internal hemorrhoids are hemorrhoids and their causes are complex, generally believed to be related to spicy dietary stimulation, long-term constipation, and sedentary, which affects blood circulation and causes the veins near the anus to become congested and swollen, forming hemorrhoids. Most of the painful internal hemorrhoids are caused by local edema, erosion, infection, impaction or even necrosis, so you can go to the anorectal department of the hospital for examination to determine the cause and condition and choose the appropriate treatment. Generally speaking, if you visit the doctor in time, the internal hemorrhoid is only edematous and the pain will disappear after the edema is eliminated. You can promote blood circulation by taking a warm water bath or applying a hot compress to eliminate the edema, or you can use hemorrhoid cream or hemorrhoid suppository to relieve the discomfort. If the internal hemorrhoid has localized erosion or infection, anti-inflammatory drugs such as cefaclor and tinidazole can be used under the guidance of a doctor. If the pain is more severe, you can use ibuprofen or other pain medications. If there is already significant internal hemorrhoid impaction or necrosis, prompt surgery is needed to avoid delaying the condition.
