Based on some of your other comments, it would be interesting if you logged your blood pressure and pulse throughout the day. Once in the morning, before/after meals, evening, and whatever times seem like they may be relevant.

I got a simple automatic cuff type from the grocery store. They make some that can do it on your wrist too, which is a little easier to carry around. Mine has a history function. Smart watches/trackers can monitor your pulse more often.

Check your blood work. I get all the details in MyChart (Epic) and can even compare from previous results. If there isn’t an app, get your records and input it manually in a spreadsheet or other app that hopefully doesn’t harvest your data. If they are not doing regular blood work a couple times a year, they are doing you a disservice.

How is your sleep? You may not be sleeping as well as you think. This is priority 1. Wash your sheets. Clean sheets are awesome.

You could be depressed or have an undiagnosed mental illness. This is ok, but you have to talk to someone. It is hard as hell to make that phone call, but your mental health is worth it. Your mental health is worth everything. I did not check if you were female, but note that birth control can cause this shit. Hormones suck.

I think you said you were in pain or discomfort? If you are, take notes on the type of pain, where, how often, duration and anything you were doing. By the time I get to the doctor, I often can’t visualize or remember the exact sensation. You could easily have something in your environment bothering you, a food allergy, gall bladder issues, thyroid, or a whole host of random shit. Switch to fragrance free laundry detergent. Maybe cut out caffeine. Just be sure to only change one thing at a time.

Don’t let doctors gaslight you or downplay your issues. Advocate for yourself and take notes. You can even have a friend go with you to the doctor if you have a lot of anxiety. They can take notes for you and potentially give insights and ask questions you may not think of.
