the last two times that I have exercised (specifically treadmill running) I have an odd sensation in my lower lip and both thumbs. Today I ran 3 miles and the last quarter mile it developed. It feels like my lower lip is pursing slightly involuntarily. When I look at myself it looks funny. Like I am holding it that way. I am able to smile fully, I have full feeling in it/no numbness. It went away within 10 minutes of stopping. Both of my thumbs turned in as well. I was able to straighten them without a problem but when I relaxed my hands as I ran the thumbs pulled in. Both symptoms stopped with 10 minutes. No pain associated or heart palpatations. Feel fine otherwise.
