For as far as I can remember, my hands have been very cold all the time. My nails are pretty small and have vertical ridges. They are also blue most of the time. My feet are cold most of the day as well. I have also noticed at times, although not lately, where my entire leg would start to go numb when just sitting down. I am just wondering if this can be a sign of poor circulation? And to add on to this, I have noticed that my short term memory can be a problem sometimes, and I get headaches more often than normal. Maybe it is just because I'm sleep deprived. Any help would be appreciated. Thanks.
