That's fantastic Dave. You're a quick healer. But, your Physio is right, slow down. You don't want to damage the tendons and ligaments, very fragile having been cut, yanked and moved about. Slow and steady wins the race in recovery. Mobility not all that great. Left thigh is totally numb, no feeling in it whatsoever. If I stand too long the leg just gives way. That won't change after the op unfortunately. The op is to secure the posterior side of lower back which is crumbling away. Another 8 screws and 4 rods going in. Hopefully faster recovery this time as it's keyhole, or as he puts it "I'll make the cuts as small as I can". He said that the last time and I ended up with an 7 inch scar!!! You take it easy and don't over do things.
