Physical Therapy & Muscle Relaxer??

Leah-Rae
I had my 28 week check up today. I've been having really bad hip/pelvis pain. I have scoliosis so we all knew there would come a point where I'd experience pain. My obgyn said it was a mixture of pelvic girdle pain and my scoliosis not support my hips and lower back. So, now she has me taking a light dose muscle relaxer so I can sleep pain free. Which has me a little nervous. Plus, physical therapy. Has anyone had to deal with either or during their pregnancy? Can you give me any insight on what to expect?
