Hi and welcome to HCM. Thank you for your querry. It sounds like stomach issue. All this is caused by high acid secretion which is found in gastritis, GERD or hiatus hernia. These disorders can cause such difficulties and you should do gastroscopy to evaluate this. Symptoms that are experienced in such conditions are pain and tightness in upper stomach, bloating, breathing difficulties, heartburn, feeling of lump and sore in throat, gurgling sound in throat, fatigue and loss of apetite. Symptoms are aggravated after meal, long sitting, leaning forward,stress and anxiety. In the beginning this is treated by changing dietary habbits. You should avoid alcohol,coffee,smoking,fats and fast food, carbonated drinks and eat more milk and milk products, fruit and vegetables,boiled food and natural beverages and teas. 1 hour after meal you should not sit or lay. Also lay with elevated upper body. If you are overweight you should do often exercise an dlose weight. Second option is gallbladder stones and you should do ultrasounds to rule this out. WIsh you good health.
