At this time, there is no option that will allow you to add a custom tracker and select your own units, name, etc.
For certain symptoms that don't require a specific unit of measurement to track (ex. 1-10 scale) you can choose a tracker that includes this option such as "headaches" and after you add the tracker, you can go back and edit the name to reflect what you are tracking.
Tap on 'More'
Tap on 'Health Trackers'
Tap on the pen icon of the tracker you want to change
Select 'Edit Health Tracker Name' and make your changes to the name
Save the changes
