Your urine should be a light yellow color. (Note: recent food/beverage consumption can temporarily alter the color.)
When you use the bathroom generate spittle in your mouth. Lean over the sink or toilet and let it slid out of your mouth. It should do so smoothly and with little to no residue left hanging.
If both of the above aren’t true then you’re dehydrated! Aim for drinking half your body weight in ounces in fluids a day. 150 lbs. = 9 cups (8 oz.) per day.
Do that and if you find that you still can’t sit through dinner without pain please do see your PCP.
I'm an American and work in healthcare. "PCP" is a common way to abbreviate "primary care physician". Generally, it is not said out loud that way, but it is often abbreviated in forms and documentation.
And yes, I giggle when I see it because I'm immature!
I've at least seen/read phrases "Primary Care" and "Primary Care Physician", but I've never once heard of anyone using the acronym "PCP" for it. Not until this ccomment thread.
Asked a couple other people just now, they'd never heard it used either.
Primary Care Physician (or Provider) is, indeed, what I think the original comment intended; however, no matter how many times I've been to the ER (or A&E if you're from a more civilized country), that's not how my brain initially interprets it.
