Been doing yoga and now have tickling spine.

I've been doing yoga and meditation and for the past few weeks I have a warm, tingly tickling in my spine. It comes on whenever I even think about mediation, yoga or martial arts and if I'm doing something very "present" and body focused like tai chi then it's almost burning. It seemed to raise from the base of my spine to the middle in the first week and then has been stuck in the middle (by shoulder blades) for the past month or so.
