I need some help

I don't think this is cancer but I would like some help.  I've been to the hospital a couple of times within this year and they couldn't find anything. Would I need a specialist to find out if I have cancer?  What are some ways that leads to finding out you have cancer because they've done a lot of blood work and ct scans.  

My body has weird symptoms sometimes and my stomach hasn't been feeling right for 5 months now.  It feels like I need to throw up sometimes(I have a lot in earlier months but thats kind of stopped now) and I have some pains throughout my body now.  I have no health insurrance so I'm not sure I can keep going back to the hospital just for them to tell me its not nothing like they have before.

Hi mark, my advice would be to keep pursuing your concerns. Have you lost any weight at all without trying. We all know our own bodies and if something doesn't feel right it's better to keep going to your GP

I've haven't lost any weight but my muscle seems to be getting smaller. About how long would it take to start losing weight? Its been about 6 months since I've started feeling bad.

You will have probably started to lose weight already mark. Sometimes anxiety can give us certain symptoms so it maybe this if you have are worried. 

Maybe you are right, i'm just sad because I don't have a diagnoises yet and I feel bad.

Please don't feel sad mark. If you feel ill and no one knows what it is, it can be very worrying. Why not try writing a diary every day of what you eat and do, any pain you get and how you feel.

This could be very helpful to you and your GP.

Yeah I will, my stools the last 2 days have been dark.  Can eating greens make them that color?  What do cancer stools look like?

Not really sure mark but cancer in the bowel or pancreas makes your stool very light and floats on top of water also going a lot more maybe a sign. I am not qualified but am going on family and friends symptoms.
