Whenever I exercise, or play sports--anything physical--the night after, some part of me will become
numb or
tingle. The first day I went out to play, I took soccer free-kicks for about 2 hours to get my kick back. The morning after I woke up with my right foot numb. After about 2 weeks, it went away. What triggered it going away was stretching. HOWEVER, this is not it. A couple of weeks after that, I slowly decided to ignore that numbness and go out again.
