Hi and welcome to HCM.
Appendiciti swould be on the right are and you would have fever, and constan pain in lower right regin.
This sounds to me more like stomach or gallbladder
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. The same is for the gallbladder stones. YOu should do ultrasounds to evaluate this.
WIsh you good health.
