Hi and welcome to HCm.
Bloating and vomiting
are nonspecific symptoms,but these lumos you re feeling are definitely something that must be evaluated! You should do at least ultrasound
to rule some serious diagnosis out. Usually such symptoms are caused by gastritis
,gErd or hiatus hernia
so gastroscopy should be performed too. There is no specific cure. If you have only gastritis 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.
But as I said, i really suggest to di some imaging tests do investigate these lumps.
Wish you good health.
