I was getting ready to take my bath and took my socks off and my feet were grey a dark grey, scared the h.ll out of me. I pleaded with my husband to take me to the emergency room cause he just thought it was from my walking in the cold earlier, but I wasn't convinced at all. I gonna make this short because it's rather embarrassing. My new black socks dyed my feet! Ugh.... Im the laughing stock of the ER.
