Dear Friend
Welcome to Health care magic. I am Dr Anshul Varshney , I will shortly try to help you with my opinion.
The most common reason for itch around anus is
fungal infection.
As the area tends to remain moist / wet, the infection is easily acquired at this site.
I usually advice my patients to take tablet
fluconazole once a week and apply creams containing miconazole/clotrimmazole twice daily over the lesions.
Keep the area clean and dry.
Change and wash the clothes daily.
For symptomatic relief, you can take tab levocetrizine 5 mg night time.
Based on the available details, this is my best advice for you. You should discuss with your doctor and share my opinion , I am sure he/she will agree to my opinion. If you wish to discuss the problem further with me , you may ask through section of PREMIUM query , directed on my name.
Stay Healthy.
