Pressure in legs

I'm 35 weeks pregnant and ever since 28 weeks I've had such a hard time with my legs. If I bend down the skin feels so tight that it's going to split open. I also have dimples all over my thighs. One dr told me putting edema but the ones at my practice just say that I'm pregnant and to deal with it. It's getting to the point where I can barely walk because they hurt so bad. Does anyone else have this problem or know what could be causing it? I can't take it one more day
