Well I puked multiple times when in Ottawa, and I've been congested ever since... plus I've had painful head aches that are sharp and sudden, that actually leave me with a really tender area (tender to the touch, that is). So basically I'm probably dying, right? I'd go to the doctor but I am working two jobs and not sleeping so I just assumed not sleeping is the source of all my problems. I was really just wondering what is to be done with lymph nodes. Someone said they come about when you have infections.
