Doc, It Hurts When I Pee. . . (or How Do You Go to the Doctor?)

I wanted to ask my faithful followers (Hi honey!) a question about going to the doctor. When you go, do you go for a one specific thing, going every time something seems to go wrong with your ever aging body, or do you wait until you have a list of things?

My preference, I've determined, is to wait until I have a list of things to address. I've got an appointment in a couple of days and so had to compile a list of what I want to address. It has like 10 or 11 entries. Now, they are not all "Oh my gosh, can we fix this please now please?" things. A couple of them are just questions it occurred to me I should ask. Like about my workout routine. I know everything says check with you doctor before starting an exercise regimen, but I've never done that because

A. lack of doctorial access

B. Duh

But since sometimes when I exercise, particularly with isometrics (which seem to cause big old blood pressure spikes), my head feels like it's going to explode, I figured I'd go ahead and ask for their advice. 

But a couple of them are actual medical concerns, like the fact that I"m pretty sure I've been able to feel my blood pressure increasing over the last month and a half to the point where almost anytime I get up, I get dizzy, and if I'm already up, reaching above my head causes pressure in my skull and brief dizziness. That's probably bad. I just don't know if it's big bad or little bad. And then there's the headache (that seem to coincide with the blood pressure thing) that lasted from before November, through November, into December. 

I'm trying to figure out if my preference is due to my never having easy, regular access to a doctor for most of my life. Up until a year, year and a half ago or so, if I needed a doctor, it was the E.R. for me. But man, I'm not going to the E.R. unless I feel it's an actual gods damned emergency, because I don't want to draw time and care from people who are having  actual emergencies. But now, in theory, I can go to the doctor whenever I want, even if it's a little sniffle. But it still feels like I'm taking care away from people who probably need it more than me. 

But it's also possible that my preference is just because I'm the way I am. Or that somewhere in my mind, I think I've only got x number of visits, and I don't want to waste them by going one time for every single thing. 

Anyway. How do you approach it?

UPDATE:  Doctor said it is okay for me to bring a list of things to address. As a result of that -
1. I get to stay a night at Community for a sleep study.
2. I get to go see a neurologist for the headaches I've had for pretty much as long as I can remember.
3. I get to get my chest x-rayed again. I don't think they cared for the results of my breathing tests.
4. I get to go back and get more shots in my back.
5. I'm okay to lift weights and do cardio, I just need to ease into them (little late on the weights).
6. It's entirely possible most of my problems would be solved if I quit smoking and got good sleep on a regular basis.
7. Doc says my situation all considered, looking into e-cigarettes is a good idea for me.
8. God damn, they took a lot of my blood today. I'm pretty sure I need that shit in me, not in vials in a cold box somewhere. Take all the urine you want, but leave me my damned blood!
