Glad you went.
I am guilty of handling things on my own - I have frequent bowel obstructions.
Its just SO annoying sitting in the waiting room for hours, being in pain, when you know you can have a nice heating pad at home, in bed, with at least some TV to keep you semi distracted.
My ER visits go something like this
Me: "I'm having an obstruction, I'm in alot of pain"
Them: "How do you know?"
Me: "Because I've been here 4x in the past year for the same thing and I know. Please get some fluids in me, and I'd like something for pain"
Them: "Lets do an xray"
.....
Them "Yes, its an obstruction"
Me: "No Sh(#%^@t. May I please have some morphine now?"
Now I've been so old hat at this that I don't even care if they think I'm a drug addict. I just say "I need morphine. I know it works, Ive been through this a million times"
While you get to know your own body and its symptoms, its good to get looked at.
BTW, I would ask your Dr. for a script for some pain meds. Not that you should self-medicate when something serious goes on, but I for one am much happier, safer feeling, that I have Vicodin in case I have some minor pain that Tylenol doesn't fix.
