Boots symptoms and conditions

Please email me or respond if you have found this. My little toes go numb, like they lose circulation or get too cold... I thought it was my boots were too tight...and one day it happened I was only on the sugar pills. But just now they were yellow no blood color and the bottom of my foot was yellow and pink.. I tried everything to get them feeling normal, they moved but they were stiff. I put them in front of a heater and massaged. After 20 minutes total they have gotten back to normal. I read that this could possibly be a side effect. This is my second pack. The first pack I can recall no side effects.
