Respected Sir For the last few days i have a feeling of burning sensation on the skin on the left side of the lower abdomen just below the naval. There is no blister or itching. Even when not touch i get the feeling of burning sensation . I don't have diabetes or thyroid problems.but burning is not very severe. It is mild but feeling awkward. But few days back before it happened i had a feeling of burning sensation inside the left side of the lower abdomen. And it happened when I turned left or right during sleeping. The feeling is like sudden electric shock burning and it is  subsided within a second and again it happens sometimes.it is also happened when i suddenly stand up from sitting and when suddenly i sit.please let me know what is the cause ?whether i have to take medicine or it will resolve on it own
