My legs are burning!!

Heather
Hi mamas!! I am currently 23 weeks pregnant and just returning for work after being on bed rest for 4 weeks. I noticed a couple days after I started working a burning sensation on the outside of my upper right thigh when I started moving around a lot (im a store manager at Starbucks so I'm on my feet all day.) Has anyone else experienced this and how did you make it stop?? It is in the fattier part of my leg and I have the lovely privilege of sporting some spider veins now that are numb to the touch- im thinking the weight gain has something to do with the burning. Anyway any insight would be awesome. TIA!!
