I have a small pimple near my anus it pains when I try to touch it may I know the solution

I recommend using an over-the-counter cream containing 2.5% hydrocortisone to reduce inflammation and pain. Apply a thin layer of the cream to the affected area twice a day for up to a week. Additionally, you can take an over-the-counter pain reliever such as ibuprofen to help with the pain. If the pimple does not improve or if you experience any worsening symptoms, please consult a healthcare professional for further evaluation.
