What is causing these tingling sensations in the anus and what can be done to make it stop?

It is possible that itching in the anus could be caused by parasites such as pinworms. To confirm this, you can conduct a "scotch tape test" by applying a piece of scotch tape between the buttocks at night to check for the presence of worms. Alternatively, the irritation could be due to poor hygiene. Using unscented wet wipes, a wet washcloth, or a bidet for hygiene, avoiding vigorous rubbing of the area, and applying a protective cream or zinc-based paste may help alleviate the symptoms. If these measures do not improve the condition, it is recommended to consult a doctor for further evaluation.
