I'm sorry to hear about the discomfort you're experiencing with the rashes under your legs. Rashes that are round, circular, itchy, and darkening over two months could be due to several causes, including fungal infections like ringworm, eczema, or other dermatological conditions.

Here are some steps you can take:

• Avoid scratching to prevent further irritation or infection.
• Keep the area clean and dry, as moisture can worsen some skin conditions.
• Use mild, fragrance-free soaps and avoid harsh chemicals on the affected skin.
• Over-the-counter antihistamines like the one containing Pheniramine maleate (such as Avil 50 mg) may help reduce itching, but these should be taken only after consulting a doctor.
• Since the rash has persisted for two months and is changing in appearance, it is important to see a dermatologist for an accurate diagnosis and appropriate treatment. They may perform a skin examination or tests to identify the cause and prescribe antifungal creams, steroids, or other medications as needed.

Please consult a dermatologist promptly to get a proper evaluation and treatment plan tailored to your condition. If you notice worsening symptoms like spreading rash, pain, swelling, or fever, seek medical attention immediately.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
