After Laying Out In The Sun Too Long I Ended

After laying out in the sun too long I ended up with a bad sunburn. (I'm 26 weeks pregnant) and not fair skinned at all - this was my first sunburn ever! Anyway, ankles swelled and around inside of my knees. One leg is now purplish around knee and starts going numb after standing too long. I've been keeping it elevated as much as I can and have been icing it. Also called my dr and she didn't seem too too concerned. Any other advice?
