A recurrent perianal rash can be fungal or irritant/contact dermatitis; hemorrhoids alone usually do not cause an itchy skin rash. The persistent firm area also needs direct examination, so do not keep applying Castor MF or steroid-combination creams without a diagnosis. Start with a dermatologist or general surgeon/proctologist; a physical examination is appropriate. I can assess the symptoms and guide treatment through a consultation.
Next Steps
Arrange an in-person dermatology or proctology review, especially because it keeps recurring. Keep the area dry, wash gently with water and avoid fragranced products, scratching and tight clothing until reviewed.
Health Tips
Seek earlier care for rapid growth, ulceration, pus, bleeding, fever, severe pain or a change in bowel habits.
