Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain Anal fissures occurs due to a small cut or tear in the anus and extend up the anal canal.. It can occur due to causes like very hard stools and pressure applied to pass the stools can cause tear of the specialized mucosa of the anus known as Anoderm.. Other causes can be excessive diarrhea, putting an anal thermometer or endoscope etc in the anus.. It can also occur post childbirth.. Crohn s disease is also another potent cause for anal fissure.. I would therefore suggest you to consult an Anorectal surgeon and get evaluated as the exact cause of the fissure needs to be ruled out and treated accordingly to prevent further increase in symptoms and treatment of cause can relieve.. He can investigate clinically as well he can advise you a Colonoscopy or Sigmoidoscopy and confirm the cause. He can advise you treatment that will relieve the underlying cause as well as treat you to relieve the fissure.. You can be advised to apply topical anaesthetics like Lignocaine gel.. Calcium channel blocker containing ointments like Diltizem can be advised as it will dilate the blood vessels in the area and improve blood flow that will initiate healing.. You can be advised to take stool softeners like Docusate and increase fibre intake that will also smoothen the stool like Psyllium and methylcellulose.. You can also do Sitz bath by sitting in a tub of warm water 2 to 3 times a day especially after bowels.. You can also take painkillers like Ibuprofen if there is pain.. In case of no resolution surgical treatment can be advised.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
