Alright, I'm a 17 year old male whose 5'9 140lbs (Rules out obesity), the past couple days I noticed a tiny bit of bright red blood on the toilet paper. My environment with classes all day involves sitting on uncomfortable chairs, and then working in a computer lab after involves more sitting uncomfortably. Also I've been having eczema type skin lately, not around anus just thought I'd mention it incase it could be related.

Do I have a hemorrhoid? I'd rather not go to a doctor if I didn't have to, although I will if necessary.

Thanks
