Can anxiety really cause this much

I've been having some anal problems ( sorry for the personal info) pressure in that area especially when I'm walking it feels like hemmroids but the doc didn't see any on looking , he doesn't seem worried but I've had an ache in my lower back and my stool the past two times has been small and lose I'm 37 and no history in my family of bowel cancer but with my health anxiety I'm convinced it's that any advice would help

 I know, health anxiety can do a number on your mind! 

 have you had your yearly physical? Is that what you just had  done or was that appointment just for the issue you're concerned about? 

I'm asking because with the yearly physical they can do an overall check, bloodwork, etc. if you're really concerned, the sure test to detect  issues with the bowel would be a colonoscopy. 

But really there are many causes for loose stool that are not serious, such as diet etc. And there are also many causes for aches in the lower back  like lifting, straining, poor posture when sitting etc. .

 or you can always get another opinion. Not sure if you saw your family doctor, but you can visit a specialist to see what the doctor thinks. 

 everything is most likely fine but for your peace of mind you could get another opinion. ❤️❤️❤️

Thanks for the reply, it was just for the things I'm worried about, I google symptoms all the time, it always makes me worse even though I think it will help,

Then more I think about it the more symptoms I get it's horrible. I may talk to the doc about an colonoscopy but recently had a camera down my throat because I thought I had stomach cancer so don't want to go through that again it was hell waiting 

I'm no dr but I don't think anxiety would cause that hard to say what it is sorry if I'm not much help I just hope you get to feel better
