There is sometimes a point in practice where this can be confusing. As we become more aware of sensations we tune into the flow of energy within our body. Sometimes this energy gets jammed up at certain places in the flow and can cause discomfort. Usually the jam eventually moves on it's own so noting it and doing nothing about it is fine. Sometimes the jam stays and increases and can become a symptom of something that needs more attention. Over time we become more skilled at telling the difference. Not everyone feels these jams so they are often dismissed by those who don't have this particular sensitivity...just ignore these folks. It is useful to become aware of these energy channels. Here is an example of a couple of meridians that are giving some people some trouble at this particular time of the year:

Pairs of meridians are associated with seasons:
Fall: Lung/Large Intestines
Winter: Kidney'Bladder
Spring: Liver/Gall Bladder
Summer: Heart, Small Intestines
Late Summer: Spleen/ Stomach
Each set are particularly active during the associated season. Knowing this we can sometimes observe/understand odd sensations/pains as just being the meridians clanging a bit at the transition period between seasons and at the peak of seasons.
