Does the Law of Karma “know” when we are working on a karmic issue via the Lightworker Healing Protocol and Deep Subconscious Memory Reset, so it won’t cause a symptom displacement if there is also use of medical support or another technological adjunct that might mask symptoms but leave the underlying, causal, karmic trauma untreated for the time being?

The answer is both "yes" and "no." It is complicated, but it is mostly acting on the energy of the current moment. So the possibility, or even promise, of future healing cannot be assumed to keep karma and its effects in abeyance. This is why the symptoms are the last things to change. You cannot borrow from the future when it comes to the Law of Karma, to bargain your way out of the problem. That can be done with divine grace, and that would require a direct involvement of ours, to override what the Law of Karma is doing and impart healing energy to balance the books, so to speak, and save you from any adverse symptoms.
