Good Afternoon, I have regular stomach pain on lower side, ultra sound is fine with grade 1 fatty leaver, please suggest what all test I do, to detect all problems, i am facing this from last 5 years, all all medicine fail to give any solution

My wife has complained twice in last 15 days of a severe pain in the left upper abdomen . No dizziness or sweating associated but only severe pain. No earler complaints of that nature was reported. She has occasional acidity problems and sleeping towards left side causes some times pain whenever spicy food is taken. But she avoids spicy food though very much fond of. She engages in some times mopping and cleaning activity of house. Both times ,pain occurred in morning between 7 Am to 10AM. I would like to know possible resaons and necessary checkups to be made. Right now she is in UK and is scheduled to return by end of the month. She is not covered by the National health Scheme of the local Govt , though has a travel insurance.
