Gabby, I don't recall anything about it in any of the first three levels.
Just as a reminder that SFQ and healing qigong in general is about finding and clearing qi blockages. It not about diagnosing or treating medical conditions. Taking in the information about a person conditions is valuable but blockages can originate far from any physical manifestation.
Why do I say this? Mainly because SFQ isn't a recipe for healing. We don't treat medical conditions. What me do results in a better flow of qi and this promotes better health. Yes, there is a legal side to it and you don't want to come across a medical practitioner. However, it is important to focus on what you are doing with SFQ. Doing this will help you from interpreting your results based on limited observables.
The above is where I ended up, after recalling the last few sets of questions on the forum. Like, what do I do for condition X. Then I searched my knowledge. Was in the information in level I (the basics of helping yours qi balance and flow). Was it in Level II (the basics of finding blockages in others and clearing them). Was it in level III (advance levels of developing your qi and working with others). And my questimating what I think is in level IV. Then I released the basics of helping people with blockages of any kind are in level I and II, and we should stop looking for the recipes and use the tools we've been presented and work on our six keys of success.
Gabby, I'm sorry you're not getting the answer you were looking for. I do hope that you find what you need.
You are perfection.
