Usually hands are an important energy "discharger/detector" (remember how many feelings you get from holding a child's or your loved one's hand).
In many asian arts such as Tai Chi or Qi Gong you use hand motions to cleanse yourself. Similarily, remember the martial artists breaking bricks not with their feet or head first, but with their hands.
In many cultures, including my own, there is something known as "hexes" and negative energy that gets transmitted to you by someone else that is envious about something (related to you) and this manifests as a sudden change of disposition or literally sickness, especially in children or even animals (in latin countries this is usually more common). To help someone that has been affected by this you say a prayer and massage the person's forehead (which coincides with the third eye that easterners/the asian people talk more about religiously-wise -the chakras & co). So here again you have the power of thought and the hand as a medium.
The japanese people also have a very interesting belief about hand-written charms as having a big effect (depending on the case).
So what I want to say about this is that what you might feel should not be abnormal :D Also think about massages /energy massages. When doing it, you feel the tensed areas through touching. Energo-terapeuts (not really sure how they're called in english) also use hand motions to channel energy or to create paths. Animals respond very well to energy expressed through the body/hands as well (dogs, cats, horses...) So yeah... try writting. Try drawing. Try related things when you feel stuff accumulating :D
