Hi Nacho,
It is good to hear that you still pursue a practice. Two years is a good amount of time, and we all have more to learn! Being more energy sensitive is a good thing. Sometimes difficult to experience!

Regarding your original post:
- No debate here... You didn't get a coldsore during your session, in the sense of it being a negative result of the session, or, anything regarding negative energy present from the outside getting in.
- Energy blockages , when released, or partially released, or stirred up , or touched, can produce unpleasant side effects, or physical manifestations, or feelings. It can be, so much so, that it really challenges the person to want to go forward. It doesn't feel good, so why go there.. Self healing can be very challenging, and one can come to very unpleasant experiences during the process. It is critical to define sensations, post session, post clearing, as a 'healing' process taking place, regardless of the sensation. It could very well be pain. If the mind starts to go negative, cut it off before the thought completes. Support the healing process.

- Being cleared by a practioner or a master, during a session, 'on a physical level', is the same as doing a session of active qigong or inactive, where you have focused on clearing blockages and gone through the steps, empowering them with your intention. That is all it is. The healer detects blockages and removes them. Some people are self empowered, some prefer outside help, some utilize both.

- Good work done can easily be undone by one's own negative thoughts, doubts, fears, thought patterns, behavior patterns, reactions to things, environment(including relationships)...

- A qigong practice is a lifestyle. You shouldn't look at a single or isolated session and judge it(discernment is okay, and different than judgement charged with negative energy) You are outside the practice of mindfullness(non negative thinking/manifesting) at that point. If your knee hurts, and you have a session to clear it, and then you judge the results negatively, or look for negatives, or pain, or do ANYTHING other than support the clearing and healing process, you can easily undo the benefit of the session. It 'is', our individual responsibility to heal ourselves. Going to Master Lin is an opportunity for support in you helping yourself. If you don't support the healer helping you, it is hard to make clear progress, or any progress.

- The spiritual aspect or potential within a session is not as easy to define. Again, nothing negative happened outside your own choosing to look there. There is a channeled aspect to working with spiritual energy. Often something comes in and is 'given' to the person needing help. What form that gift takes? what seed is planted, or possible understanding and growth,,,, the healer often doesn't know. It is a blessing though...

-It takes focus and intention to create, build and/or spread negative energy. This is simply not part of the SFQ picture, Master Lin, the healing center, or his private healing space.

- If one is overwhelmed with the nature of a condition or blockage, it is okay to see a doctor and move on both fronts. If the blockage involves how you feel, emotionally, or how you see things or experience reality, it can be quite challenging. Medications may not be tuned in, or help. From a qigong standpoint, patience is required, diligence... Continual practice. One's mind and thinking can take you two steps backwards, while your practice brings you one step forwards. No self judgement on whatever has gone down... New beginnings are there, anytime. Let it go...go back to your practice.
Nacho,,,,It would be nice to see you again and catch up. I am busy through the next few wks, but drop me an email and let's get something on the calendar.
love,
