Okay, I'm new so I just want to make the best of my $50 copay when I go to the doctors. Been having chest pain under my ribcage on left side and back spasms for quite a few years. Just felt a bump about dime-size in diameter on the left side of the back of my neck. I smoked for 2 years and recently quit about a month ago. Any ideas? Should I get an xray or blood test? I'm a female 22 years old.
