I Had Left Hip Replacement On 12-31-15 And My Low

I had left hip replacement on 12-31-15 and my low back problem (L 4and L 5 ) has gotten worse ,especially on the left side ! My groin still hurts on left side as well and I feel "grinding/popping" when i move my left leg certain ways.I've been to my chiropractor 4 x and done 'decompression" machine with no relief !I do yoga 3-4 times a week as well as cardio 7 days a week - prior to surgery I was able to do 8 yoga classes a week with my bad hip - what can I do to relieve this pain ? Or is something else wrong ?
