I had hoped someone would have responded to this by now, so I guess I’ll give you my 2 cents on this. Perhaps this will stimulate other responses. I have found that with cold there is some kind of healing needed or healing being done. In your case it could be a healing or channel being worked on. The work you do at the time you do it does not necessarily end at that moment.
If the problem was significant enough I might apply a little massage to that point and send energy to help balance it. When sensing the energy field of someone if there is a cold spot in contrast to the rest of the area then I would send energy and or remove the block and energetically fill the whole so to speak. I suspect that this is something covered in the other levels of qigong courses. Perhaps someone with more experience in the higher levels can elaborate on my back issue and the cold spot on the calf? Anyone? Bueler 
?
