Left side pain

[CMB58]

I have had so many problems in the last couple months that I really don't know where to start.  My latest is a pain in my front upper left side right below my rib cage.  It's not constant and it's not a bad pain but just enough to bother me and worry me.  I am also having bad lower back pain that comes and goes.  I have had changes in bowel movements going back and forth from constipation to loose stools.  I recently starting having dizziness on and off throughout the day but the doctor thinks it's an inner ear infection.  I woke up this morning with nausea but it's hard to tell if it's related or just nerves. I also had an abnormal pap but have recently had a repeat that was normal. I do have back that has T-4 and T-5 that's bad and gives pain but don't think this has anything to do with left side?Im 56 years oldand it has been one thing after another ever since.  Does anyone have any ideas on the pain in my left side?  Thank you,CMP
Thank you,

Hi, there could be many causes for the pain you are experiencing. If the pain starts at the back and goes down to the front of the abdomen, it could most probably be a renal colic. This happens when urine is trying to pass through an obstruction usually a stone. But this pain is very severe and colicky. This can also cause dizziness and vomiting. Considering your altered bowel habits the pain could be due to infections of the bowel and bladder or inflammatory diseases of the colon. Only further investigations like colonoscopy and stool examination will help identify the cause. Please follow up with your doctor. Regards.
