Can You Have Back Pain With A Negative Urinalysis Lower Left Back Side Pain, Constipation? Pancreas Problem?

Lower left back side pain, constipation? Pancreas problem? - can you have back pain with a negative urinalysis

I fear that this might have pancreatic cancer. : (
For several weeks I had pain in my lower back left side that sometimes radiates to the abdomen or the shoulders and upper back. Nothing too serious, just minor aches and pains.

I was not very active or exercising lately, I must emphasize.

I had constipation and was forced to urinate and about the same amount of time.
I saw several different doctors that I have urine tests, urinalysis, and urine cultures negative. However, I still have discomfort when urinating or later.

I did lymph nodes in the neck, throat near my windpipe by the same amount of time and saw a doctor this as he felt around and said it was viral and autumn. She fell, but he is mobile and rubber-like feel.

This reality has not happened to me, and I am concerned. What is possible? I could really have some suggestions that I am constantly frustrated by doctorsLy exclude this possibility.

I realized that I lost weight around my stomach area, but when I inflated it as and when completed in air or gas. I am very concerned about this and not in the way of my holiday.

Is this a problem of the pancreas?

Please help! Thank you. I'm only 18
