It's understandable to be concerned about any discomfort you're experiencing. The symptoms you're describing, such as pain and skin changes in that area, may indicate an infection or irritation. It’s good that you’ve been using Canesten as prescribed, but if the condition persists or worsens, it’s important to consult your dermatologist. They can assess your symptoms more thoroughly and determine if further treatment is needed. In the meantime, try to keep the area clean and dry, avoid irritants, and wear loose-fitting clothing.
