Slowly, physio says my back is feeling looser to him, a good thing, but because I'm using it so heavily lately with house projects etc it's hard to tell.
I'd say the frequency of which I get the sharp debilitating stab has lessened somewhat. My glute medius strength has substantially improved through the band work he asked me to do which will help stabilise my pelvis. I'm seeing him again tomorrow so I'll have another update then. In the meantime I've just being doing regular bench, chins, dips and some calf raises and lunges to keep everything moving. Plus all the house project work.
