I am sorry to hear about ongoing quad pain @tkrfail21. In my case I had lumbar stenosis at L4/L5 and it eventually progressed to neurogenic claudication from the nerve compression...pain started at 2nd toe came across top of foot, around by ankle, up outside of leg and above knee made a hook towards inside of knee. The only way I could relieve the pain was to do "forward leaning squats" which progressed to having to do after only walking about 50 feet. By time I reached this point, it was surgery that relieved my pain. My second toe is still tingly feeling but all the other pain stopped. It was a HUGE relief. I did over 5 months pre-surgery PT which kept my abs, legs, hips strong and my balance optimized for surgery. Things I did that did NOT help: chiropractic care MEDX lumbar treatment, pain management outside of Mayo clinic because they weren't offering me the correct injection, e-stimulation.
Wishing you the best
