Pcos + back pain, plz help

Hi

I am mom of 2 kids. First one was normal for me, seco d is c section. I brought my second one all one. My periods was very heavy for almost 7 months. I consulted my gynecologist , she diagnosed that I am having Pcos. I am 5.3 weighing 60 kg but i have big tummy and having hairfall. Inbetween i had a severe backpain, when i consulted doctors, each one told one reason, one told its bcoz of restlessness, another told its due to calcium deficiency. when i consulted ortho, he told you have slight slip disc, u do exercise for toning your tummy. I want to reduce my weight for pcos, but with backpain , how it is possible. I want to have to second opinion from good ortho. Do anybody knows good ortho in sarjapur outer ring road.I was doing power yoga for 1 month for pcos, then only severe backpain started.
