Pain in your lower back radiating out to your hip and down your leg usually indicates neurologic/disc/spine involvement. You should go to the neurologist.
If it is neurological/disc, heat may not be helping. Try ice packs, the logic is to reduce the swelling of the disc pinching/compressing the nerve.
Ya, I have a zipper back also. L5/S1 disc blown. Blew it off, big mistake. Made the surgery (laminectomy/discectomy) and recovery worse. Still don't have full sensation in the outside of my calf after 20 years.
The exercises in the OP are the same/similar to the PT I did post surgery.
Good Luck.

Being told you're delusional does not necessarily mean you're mental.
