The first card we will analyze is the Nine of Swords. This card represents a time of crisis and uncertainty, but also a broader vision. It could mean that John is facing a difficult or challenging time, but that he also has a vision of how to overcome it. It means that there is something that needs to be addressed, but that there is also an opportunity to turn this moment into something positive. The good thing about this situation is that John has the resources to deal with this moment of crisis and he can find new ways to proceed.

The second card is the reversed Ten of Swords. This card indicates that there is something blocking Giovanni from achieving his goals, but also that there are opportunities to overcome him. It could indicate that there is something preventing him from feeling well, such as a physical or mental problem. It can also mean that he himself cannot find the right motivation to take care of his health. He therefore indicates an emotional or mental block that prevents him from progressing towards health and well-being.

In conclusion, from the interpretation of the two tarot cards we can say that Giovanni could currently be blocked by something that prevents him from feeling good and achieving his health goals. However, the Nine of Swords also suggests that he has the resources to overcome this block and turn it into something positive. So, the answer to the question is: yes, John can heal and improve his health, as long as he is determined to face the challenges he is facing and takes matters into his own hands with strength and determination.
