Thank you, appreciate your reply.
Hi there!
Well, without a detailed clinical evaluation it would be difficult to determine the cause of your symptoms. Possibilities that may need to be considered include dietary causes, GI infections, inflammations, GI motility issues, GERD complications, growths/ masses, hormonal/ endocrine issues, medication side effect etc. I would suggest getting this evaluated by a primary care physician or a gastroenterologist for an accurate diagnosis and appropriate management. Meanwhile you could try taking some OTC anti-emetic and anti-spasmodic medications and see if these seem to help.
Hope this is helpful.
Take care!
