Leg Numbness

I'm currently 26 weeks along. About a month ago I started noticing my right leg around my thigh going numb. Talked with my ob and she mentioned baby could be on my sciatic nerve. Over the past week my right thigh is constantly numb and sometimes when I stand it causes a brief amount of pain like my muscle is being stretched. Anyone else dealing with anything similar? Anything I can do to try and get some feeling back? I've tried some stretches as well as laying on my left side.
