I've had relief from strecthing hamstrings and thigs primarly. Hatha asanas that stretch back and other part of legs help too. That pain is a symptom of tight backline and generally too much sitting or something else that is detrimental for posture.
Might want to try some of what this search has to offer: https://www.qwant.com/?q=yoga+for+sciatica+pain&client=ext-firefox-sb&t=web
I never avoided KY during the pain. It still exists in very minor form, but I am working on it daily so I don't really worry.
I've suffered as well. What people don't realise is that with mobile phones people are always leaning and bending forwards.
The head is heavy and weighs about 10 pounds or 4.5kg.
I've never managed to correct it myself by lying in the semi supine or doing stretches for example.
And I have had teachers that are not that good and just want your money.
But a good Alexander Technique teacher could put your back right straight away just by leading your body back into its natural state.
I cannot believe it but just the head and neck positioning can put vast pressures right down your spine.
It's all about posture. If you're in natural alignment and not doing to your body what it shouldn't be. Like bending out of place your back problems resolve themselves.
I'd say stay away from chiropractic because that's dangerous. And try some Alexander Technique teachers out.
Sorted my pains. And I'm aware of people holding their heads forwards and the hunch back they're developing.
It's not rigid straightness but correct alignment so the whole spine right up to the occipal (pineal gland) joint can naturally support itself.
