I reread my reply and wanted to make sure my response was clear. The idea is to work on feeling energy. If someone came to you and said they had a sore shoulder, you don't really listen to that and use sword fingers on their shoulder. You feel for energy blockages, that tells you what you need to know. The shoulder pain could result from a blockage in a completely different location.
From another perspective, if I deep cut, I wouldn't sit and bleed and use sword fingers on the cut. I would apply pressure, get it stitched up, then, afterwards use qigong to aid in the recovery and healing.
