Received fitbit charge 2 device as a free gift from my employer to record my physical activity and began using it on (b)(6) 2017.After a week or so of use i started having dizzy spells.At one point while driving, i had to pull off the road at one point because i could no longer see the road.Coincidentally, i had my yearly physical on (b)(6) 2017.Blood tests revealed hypothyroidism: tsh = 9.96, free t4 = 0.8, and t4 total= 4.7.I had a problem with my thyroid in the past, however, i've been off medication for over 2 years.I stopped using the device (b)(6) 2017.
