There's a DIY-ish service that can be self hosted (not sure if it's still maintained) that tracks all kinds of data in a way that you can share with a physician. It's called Fluxtream, and might take a few extra keywords to find. Written in Java+Spring. I haven't used it myself. Putting more and more of our data, especially health data, in the hands of others is the wrong direction to be moving IMO.
