Hi, 

Like many I never usually post on forums but my head it all over the place with worry. I'm a 40 year old female and I've always had an achy back (from bad posture) and recently I began getting a specific pain on the left side of my back. It was nothing excruciating, more annoying. After several weeks of it coming and going my husband suggested going to a physio, so I booked an appointment. She said she was concerned as it was middle/upper back, didn't respond to manipulation so suggested I go to the docs using the term red flags. 
I saw the docs in the 7thAugust whereby he took some bloods and put in for a chest x-ray. He told me the bloods would be looking for markers of cancer in the blood or bone but said he wasn't concerned as I didn't have any other symptoms. Now, I have lost a few lbs ( about 5-6) over the past couple of months but have been eating well and walking regularly so have put it down to that. I don't know what substantial weight loss is! 
The bloods came back normal and I went for a second physio where she said she was still concerned! So of course I have looked up different cancers it could be and since then I seem to have had every symptom going for bowl/ pancreatic cancer such as diarrhoea, vomitting, not hungry. I know I am a worrier and when I worry I don't eat but now I am concerned that my weight loss is something more and all these symptoms are actually part of a bigger problem. Oh by the way I do suffer with IBS, but never had diarrhoea or vomitting with it. My stomach feels tender and I've woken up feeling nauseous and subsequently been sick. 
I am trying to call docs again tomorrow as they were fully booked today but needed to share this as I'm convinced I must have 'C'. But don't now if I'm making myself sick through worry! Has anybody else has a similar experience?
