Hello,
Some possibilities for your symptoms are gall bladder disease,GERD(gastroesophageal reflux disease),pancreatic disorder,Functional abdominal pain syndrome (FAPS),inflammatory bowel disease,fibromyalgia and ovarian cysts.
I feel that consultation by a gastroenterologist along with ultrasound uterus and ECG(to rule out cardiac causes)will help in confirming a diagnosis as without examination,pinpointing a diagnosis is tough.
Hope it helps.Take care and pls do keep me posted on how you are doing
This feels a lot like the pain you get with gas in the intestines. But its always over on the left side.
