I have similar symptoms but less severe, with mild stenosis. That is, stiffness and soreness in right hip, TFL, lumbar spine, with cramping and burning in anterior thigh. Went the usual route of conventional MD's and physical therapy. The only thing that is helping me is a good chiropractor. First, finding a good one. Then, going 3x a week for a few months. Also, C-1 adjustments in neck are helping PD symptoms, such as tremor. Better blood flow or nerve communication, I guess.
