Thanks for the query.
I understand your concern.
The possible causes of your pain are gastritis, peptic ulcers, gastroesophageal reflux etc.
Sometimes vitamin B12 deficiency can lead to peptic ulcers and can also neurological symptoms like tingling sensation.
As you are having severe pain, better to get evaluated.
By clinical examination and investigations like endoscopy, serum vitamin B12 and folic acid levels estimation the possible cause of your problem can be identified and treatment can be planned accordingly.
