anytime if feel the slightest discomfort, i stop what i am doing and then stretch a little. I haven't had pain like I did back in October, thankfully. I do a lot of stretching. I follow a couple of doctors on YouTube. I joined Planet Fitness and use their massage chairs and their hydromassage table.. I feel a lot better. Playing some golf now....well just pitch and putt, so far no back issues. Will have to look into getting a new pillow.....anything to feel better and avoid a flare up.
Best of luck to all those suffering from back pain and sciatica.
