Severe acidity, anxiety, shoulder and low back pain and sneezing

I'm male 41 years about 72kg.
I'm suffering from the following:
(i) Severe acidity for the last 12 years. I get sour eructations, heartburn, burning sensation in the stomach even with small amount of food intake. I suffer from these with all kinds of food but oily food increases this. Also, I get a feeling of fullness of stomach specially with fatty foods. I have to take Esomeprazole tabs daily for this. I have been diagnosed with reflux oseophagitis after endoscopy.

(ii) Lots of gas are produced in the stomach leading to passing of the gas through rectum frequently.

(iii) I also suffer from anxiety and mild depression and gets irritated (angry) very easily. My sleep at night is also disturbed.

(iv) I have cervical spondilitis and as a result pain in right shoulder. The pain starts in the region between the joint of the neck and shoulder to the joint of shoulder and hands. I also get a sensation of tingling in this region.

(v) I also get a pain in my lower backside which starts with standing sometime without support or sitting long time in a fixed position. The usually gets better with movement.

(vi) I'm also allergic and have symptoms like frequent sneezing and itching and watering of the eyes.

(vii) I get a dull headache specially in the afternoon. The headache is mainly on the upper side of the head (affects the front starting from eyebrows, the top of the head). It hurts if I move my head.

Please help with the suggestion of medicines.
