The painful cortical hemorrhoids should take about a week if you opt for the clipping option. Because the cortex is mainly a connective tissue external hemorrhoid, an area of innervation of the limb that is sensitive to painful stimuli, the surgical operation should be performed under local anesthesia. And after the surgery, you also need to apply a sterile dressing, especially every time you have a bowel movement, you should wash it in time to avoid contamination and avoid inducing local inflammatory reactions that can lead to increased pain symptoms. After surgery, attention should also be paid to symptomatic treatment such as prevention of infection by taking oral broad-spectrum anti-inflammatory drugs, such as amoxicillin capsules or roxithromycin dispersible tablets. It is also important to keep bowel movements open. If necessary, you can also apply pain-relieving drugs, such as oral amoxicillin tablets or Nimesulide. During the treatment period, drink more water, eat more fresh vegetables and fruits, and also perform appropriate exercises for the anal levator muscle to reduce pain.
