The first card we have is the Five of Swords. This card represents a time of difficulty that can lead to health problems. It can also indicate that your health problem is partly caused by something deep inside you, such as a wrong way of living or thinking, or it can indicate a hidden health problem. So, in this context, the Five of Swords is telling us that there is something to take into consideration when it comes to hereditary health in your family.
The second card we have is the reversed Queen of Cups. This card represents negative emotions that can block you. It can also represent fear of inherited disease, as well as an inability to deal with health problems. So, in this case, the Queen of Cups is telling us that there may be an emotional block to deal with when it comes to the topic of hereditary health in your family.
The two cards together tell us about a more complex problem than the simple initial question. They talk to us about the need to consider both external (Five of Swords) and internal (Queen of Cups) factors regarding any hereditary health issues in your family. Based on what you've read, the most likely answer to the question is YES: you should be concerned about a hereditary health problem in your family. However, one should never overlook the possibility that you can successfully address the problem by exploring the emotional and psychological aspects involved.
