Digestive issues and chronic pain. Need?

For past 2 years I have pain and inflammation in my left upper abdomen. Also back & chest pain on left side. I feared could be related to heart but ECG and Echo tests are normal. Can't sleep comfortably on left side as I feel some pressure in left side abdomen. I Thought managing weight will improve as I went from 81kg before lockdown to 92kg after. And due to lockdown couldn't visit doc. I can also no longer eat oily foods, greasy foods or sweets as after sometime I have the urge to poop. Such oily foods are not digested and stools are also oily/greasy. Also have heartburn issue and managing with antacids. I have visited different doc and they give me pantoprazole tabs saying it should be GERD but those are not helping me. Also even with fasting my weight is reducing slowly. Also Attached few pics of latest blood report. It has elevated TSH levels, borderline high LDL and abnormal values in Liver Function Tests. What could be my problem and what further evaluation should I need?
