Does vyvanse cause feet pain

Maybe... Im having the same experiance.. Im on 30mg day, for about 3 weeks.. All of a sudden, numbness (cold) in my left arm and leg... I dont know if its just because Im so focused on work that I dont get up from my desk for 4-6 hours at a time, or if its the drug. Ironically though, as soon as I started moving/walking around, it felt like the blood returned, and the area instantly had a rush of a warm feeling?!?!?!
