Upright Meaning:
If you turn up the Four of Swords in a health-specific reading, you are likely internalizing pressures of the outside world to a point that is becoming unsustainable for your health.
As a Swords card, it is most likely pointing to mental health in the upright position. Try meditation, or counseling, or therapy if you need to step outside of the situation for a healthier mental perspective.
Reversed Meaning:
If you have received the Four of Swords reversed in a health reading, you may have ignored signs to rest and take care of your mental health too long, and now your body is at a point where it’s burnt out and is going to force you to stop and take care of yourself.
Ask yourself whether your productivity is more important than your physical and mental health, or whether you are able to step away from the work for a moment to rest.
