I am a 46 yr old female and have been feeling pins and needles in my lower legs and feet and my thighs get hot and sting, it s really uncomfortable. I sometimes sleep with my legs outside the covers as they are burning so bad. They aren t discoloured but feel like they are sunburnt. I m in good health normal weight and eat reasonably healthy. I do a desk job so I am quite sedentary although I do exercise a bit. Any help would be great as I m worried that it s something serious. It s been going on for a year but is particularly bad at the moment.
