Ah ok, I thought that was your core temp, that would be seriously worrisome if not already an acute crisis, I've never heard of it going that low. Surface temperature is next to impossible to measure accurately, it is super fluid so most likely that is an anomalous reading then. The only temperature of your body that really matters is core temp, skin temp is all over the place, from 33 on the low end to 37 on the high end depending on how much bloodflow you've got and what the ambient is (because you'll always measure partly your body, partly the air around it).
