Numbness in legs

CupcakeMama08

So for over a month now, I've had numbness in both of my thighs if I stand or walk for more than about 10 minutes. Once I sit down my thighs will go cold and tingly and then eventually go back to normal. Two doctors in my practice have told me that this is normal, yada yada, and to avoid standing or walking when possible.  Yeah, that's not really all that possible! 

Anyone else have this problem? If so, what do you do for relief? TIA
