Some of us have symptoms that fluctuate more than the stock market. In the morning you may be pain free, then in the afternoon the symptoms increase, and get better in the evening. On another day, the pattern is reversed.
Imagine if you could view this history of fluctuation like a stock market chart that was accurate to the minute. It would be a gold mine of insights, since each fluctuation tells the unique story of your health. You could trace each flareup to its origin. For example if you had a bad flareup in July, you could look back in the history and see that the symptoms started to increase on July 2 around 4:15. Then you could play detective and see what you were doing in the preceding hours, such as lifting weights, getting a massage, or using a particular supplement.
