Anal pain has to be differentiated into what causes it before deciding on the specific medication to be used. If the pain is very severe, then you can temporarily use diclofenac painkillers orally first to relieve the pain, and then go to a regular specialized hospital for examination to clarify the diagnosis. Generally the diseases that can cause anal pain are thrombosed external hemorrhoids, edema of external hemorrhoids, embedded internal hemorrhoids, anal fissure, perianal abscess and other diseases. Therefore, the treatment of different diseases is not the same, thrombosed external hemorrhoids is the best way to surgical treatment, while edema and embedded internal hemorrhoids need to be applied locally in the form of sitz baths, as well as suppositories in the form of nanoanalysis to relieve pain. If the anal fissure is mild, you can apply fumigation sitz bath, as well as suppositories to relieve the pain. If the fissure is more serious, it needs to be treated with surgery, and perianal abscess needs to be treated with surgery, and there is no obvious effect with other methods.
