HELP: red and tingly shins

babyboyL2013

This week I have noticed my ankles have swelled a little bit. I'm on my feet a lot(I'm a teacher) so it's hard to elevate them. The past two days I have noticed that my shins have also turned red and feel numb/tingly. I called my doctor about an hour ago and they want me to prop my feet up for the rest of the night, drink lots of water, and come in first thing in the morning. Baby is moving fine...kicking and rolling around as I type. The doctor said she didn't think it would be a blood clot because it's both shins but the word "blood clot" still makes me extra nervous!   Anyone had this happen before?  I'm nervous!
