Hello,
Thanks for the query to H.C.M. Forum.
I would come up with these possibilities for this type of pain in abdomen on LEFT side , these includes.
1 Left renal stone , diagnosis can be confirmed by
ultrasound of kidney.As all symptoms are suggestive of pain in the left side of kidney.
2 Second possibility may be of
peptic ulcer disease ( hyper acidity ) ,diagnosis can be confirmed by upper G I
endoscopy.Try raising he head of your bed about 4 inches above with blocks.It might also help to avoid eating or drinking 2 hour before you lie down.To control stomach acid one should not eat chocolate or spicy or fatty or oily foods.Also take some antacid but if symptoms are severe then you may need drugs like
proton pump inhibitors.
3 Next possible reason may be
pancreatitis . Get in blood examination for serum amylase and lipase.As this pain is radiating to the back so may be a pancreatic pain.
In my opinion this is not a pain of appendix as appendix is always on the right side ( one to two exception in 1 million cases on left side).
In my opinion consult another physician and get his opinion.
Good luck.
Dr. HET
