I was taking bath and suddenly two red lines appeared on my stomach (about 5 cm horizontal and 5 cm vertical). It has the same feeling of a cut. Let me explain the cut in deep. When you scratch the skin with metal that is not sharp to cut the skin then it put a red mark on the skin and feels the same as being cut. I thought the mark will heel but it didn't and atill pains like a cut. I thought that some insect must have crawled over the skin but its not the case as the mark appeared when I was taking shower. Can you please help me out with this. My age is 27 and average body but hardly exrcise and irregular food timetable.
