Hi.
Thanks for your query.
The causes of the
bloating of the abdomen alone can be as follows :
Gaseous distention of the small and / or large intestines due to a variety of causes, most common being the sub-acute intestinal infection.
Another cause can be ascites.
Whatever the cause that we will have to find, this distension causes the stomach to be pressed causing other symptoms of Cramping the back, stomach, neck pains and all the symptoms you have. This can be the reason for acidity, pains, pain in waves as you have explained.
I would advise you the following:
First of all get the following simple tests:
X-ray of the abdomen in the standing position to see whether this is due to the gases or something else.
Ultrasonography will help for other causes,
organomegaly meaning enlargement of the vital organs as liver and so.
Tests of the blood, urine and stool-Take a course of an antibiotics and,
metronidazole, probiotis and all symptomatic treatment.
You have to keep the stress and anxiety to be free from by any means like , yoga,
meditation and proper treatment
