Causes of itchy anal rash include moisture(due to sweating or frequent washing), the abrasion caused by clothing,the pressure of sitting,chemical irritants like laundry soaps, colognes and scented toilet paper,certain food irritants,medicines like some antibiotics and laxatives,infections like STD’s and pinworms,anal abrasions and fissures and skin problems such as psoriasis, seborrhea and eczema. Sometimes hemorrhoids will start off as red rash and anal itching.
From the symptoms that you are having,I would rule out pinworms,scabies,anal fissure and hemorrhoids(already ruled out).I would suggest a dermatologist’s evaluation as without examination confirmation of a diagnosis is tough.
I hope that helps. Take care and please do keep me posted on how you are doing or if you have any additional doubts. Kind regards.
Could this be an anal abscess? It feels like a hidden pimple on one's face that would itch and then the pain would increase as the pressure increased. One online surgeon suggested it could be folliculitis. I applied neosporin, with no relief. Last night I applied the lidocaine 3% 0.5% hydrocortisone as indicated and also on that area. It is at 4 o'clock on the anal rim. How much longer should I wait until I make an appointment with a dermatologist?
I feel an inside pimple on that side as you enter the anal rim but before the rectum. Could this be the cause of the itching? and it feels like it is bigger than when I felt it the other day. I applied neosporin to it with a qtip. Could this be a polyp, a cyst, a wart? If it is just a pimple could it just open by itself? How long should I let this go before seeing a Dr.? Should I see an internist, a dermatologist or what kind of surgeon?
