Hip pain that radiates from calf

[pkkenchan]

Just to make a shot...
have you tried treating the sacrotuberous ligament which link the Sacrum and the ischial tuberosity.
Also hamstrings are also a possible suspect for causing the pain....

I am making this "educated guess" because you have tried to stabilize the SI joint with improvement in standing but not in walking.

Core strengthening might alleviate the pain

I'm guessing if you are saying that the pain radiates from the calf this means that the pain starts in the calf first?? Given his age maybe just rule out intermittant claudication and/or spinal stenosis to be on the safe side!

Thanx

I'll definitely test for all the suggestions..

I hope its one of them
