I have KARAT(Marathi word) in my leg & blood is totally clot around it,all red clot blood inside skin around the infected area.

The symptoms you described, including a visible clot and redness around the infected area, suggest a skin abscess or furuncle; in Marathi, "Karat" often refers to a boil or abscess, which typically requires medical attention, such as incision and drainage, antibiotics, or warm compresses to promote healing and prevent further complications.
