I am 20 years old female. It started with the burning sensation in my upper abdomen and chest last week. But then I reduced my spicy food but after then when I had my lunch, a rough pain and a kind of heaviness feeling occurs just after eating food in my front lower ribs and back ribs like I am carrying weight. And yesterday just after laying down a unexplainable pain arises in my left front lower ribs for just a second and the intensity of pain was to a level that I screamed very loudly but it was only for a second. I recently had a cbc test which reported my rbc are predominantly normochromic and normocytic.
