QL tightness/injury

I just had a question regarding current injuries. I've had incredibly tight shoulders pretty much all my life and recently I've had hip pain/lower back pain due to a twisting motion, which a chiropractor has diagnosed as stemming from tight QLs and it's been going on for about 2 months.  I've finished the first 6 days of fundamentals and there are days the pain is worse and some better. Is it a better idea to wait til the QLs heal on their own or will these exercises help the QLs heal anyway?  I just don't want to make the injury worse but I want to progress. Thanks!
