Useful to remember when you scale up your pain scale or down. My migraines change during the day, but you can never really see when it gets worse and what symptoms are added how long the migraine lasts. When I log my migraine, it sometimes starts at level 2 and then later in the day it becomes 8 and then it drops again but the app does not remember that. I think it’s useful information to see when and how the migraine pain fluctuates
