Aoa. I have a black hard spot on my leg few inches above from ankle. It's been around here from some years and itching kafi hoti hai or itching k baad us pe kuch zakham se b hona start ho gaye hain. I don't remember k ye kisi chot se bana tha ya kese or is par kabi dard b nahi hua. Aj kal bas itching ho rahi hai. Please tell me what it is? Isn't anything serious ?
