Hi Braden and Welcome to permies!
First of all, I want to acknowledge you and thank you for being a caretaker. To those of us who need caretakers, you are the most valuable and precious people on the planet.
I second Al's excellent response. I suffer from a rare autoimmune disease that is quite aggressive and causes much mischief in my life. Because I see a variety of doctors, naturopaths, acupuncturists, chiropractors, etc. it's necessary to keep an ongoing record of what's going on. This is also very helpful when a crises occurs (because they DO occur and this information can help save my life) or when I'm traveling. Because my friend knew I had this document, I was able to be treated quickly and effectively, even though I presented at the ER unconscious and thus not able to speak for myself.
Here's what's in my "Medical Journal"
