I am getting mild pain across parallel on both left and right side of my belly button .Mainly on right side beside belly button.I am having this from past 4 years.Pain is not constant .It comes and goes.Pain is only across belly button not to above belly button.I undergone ultrasound for 3 times in these 4 years which says normal .I dont have any other problem or illness except this pain.Doctos are not able to say anything exaclty when i consult 2 urology and 1 gastroenterologist .I dont eat much spicy and oily food.I have marked the pain in image where i get.Most of the time i get in middle that i have marked.sometimes pain moves from one side to other as i marked in the image.I have also attached my reports.Please provide me the solution what i can do.
