I have this annoying red ,circular, raised, non-itchy blotch on my calf. I've had it for a total of about 3 months. At first I thought it might be a bite, and it would go away on it's own, but it didn't. Then I thought I had ringworm, so I bought anti-fungal cream, the 1% clotrimazole cream and it actually got worse. It got bigger and more red. Can you please tell me what this might be? It's annoying to look at and I want it gone. This is the only place where I have the red blotch.
