Back Pain During Pregnancy

I've suffered with lower back pain for the past five years. After MRIs, CT scans, X-rays, Neurologists etc, I was diagnosed with fibromyalgia and sciatica.

A few years ago the pain was very severe, but after removing myself from work and avoiding stress for a few months the pain eased. Afterwards I began strength training and exercising which if done regularly helped. At one point I was on prescription pain killers and sleep meds but managed to get myself off of them and was doing quite well. I also received massage regularly.

However, when I became pregnant with my first child last year the problems all flared up again. I had extreme groin pain, pain the the glutes (seriously killed!) and lower back pain. Unfortunately my daughter is almost six months old now and I still haven't gotten rid of this.

I have seen a physiotherapist weekly. I think she has put the pelvic bones back in place but now the muscles are extremely tight. I can't cross my legs, stand straight without the groin muscles pulling. I can't walk on flat ground for long without it all ceasing up. Anyway, I’m tired of spending money on physiotherapy. I'm going to try these exercises for awhile before seeking further help.

Any advice would be appreciated!!!! I don't want to go down the road of pain killers and all that again.
