Suggest Remedy For Discoloration And Itching In Lower Part Of Stomach

Hi, may I answer your health queries right now ? Please type your query here..Across the lower part of my stomach I have signs of discoloration (like a bruise), but in the past month or so my stomach has been itching across the area. The only significant change in my body has been, unfortunately, weight gain. I do not have any abdominal pain. Any idea as to what my body is experiencing?
