My guess is that the injection would keep the muscle from a spasm...then perhaps you could walk further....11 steps then maybe 12...of course they wear off although it might help getting stronger...

Now about one crutch...in my auto accident I had two major injuries...my l Knee and lumbar nerves....surgery first for the knee; 2 weeks in a wheelchair,,,,2 weeks on 2 crutches,,,,the REHAB physical therapist told me I could go on to one crutch....the twist and drag just wrenched my back and added to the lumbar injury...I did not feel the pain because all there was...was pain and meds. It just adds such an odd stress and crook to the body...my opinion.

Enlarged muscles....hmmm....how to relax them...massage...heat...I am sure you have tried the gamut...

Great news overall ---do keep trying to get about...keep us posted
hope you get more answers
