For non-severe cases of sciatica (i.e. not having foot drop or incontinence) a holistic approach of regular stretching and shifting your body's biomechanics can not only lessen your pain levels, but help it from coming back. The sciatic nerve runs from the lower back all the way down to the foot on either side of the body. Sciatica can be a result of several spinal issues, so it is important to consult with your doctor to ensure that this is not the underlying cause of your lower back pain. Deep stretching of the back and hips with follow up care to strengthen the pelvic floor and shift your gait (walking) can all help your sciatica no matter if you choose a doctor-recommended approach such as a cortizone shot/epidural or a holistic approach of chiropractic/acupuncture.
Deep stretching of the hips can take pressure off of the sciatic nerve, particularly by stretching the piriformis muscle. The piriformis connects the lower back to the hip and acts as a rotational muscle for the thigh. The sciatic nerve passes through this muscle for some of us, so when the muscle gets tight, it cuts off the nerve. Ki Hara active stretching is particularly effective for loosening these muscles, because we take the muscle from its shortened length and then actively pull it long. This means that flexbility isn't coming from a ligament or the joint, we're actually creating longer muscles--kind of like stretching taffy. You can see an example of this and its effectiveness here:
I find that another contributor in back pain is that we hold our breath from stress and become 'tightasses'. Read more about this here.
After getting more space in the pelvis, we can reengage the pelvic floor muscles and strengthen the glutes that should have been doing more work before sciatica came along. After sitting for so many years--even think back to being in school, the chair ends up supporting our weight most of the day instead of our pelvic musculature, including our bums. We end up with flat behinds while the muscles in the pelvis tighten and weaken. They then tug on the sacrum or lower back, forcing it to move in ways that it shouldn't, so it rightfully gets angry. By consciously reconnecting with the pelvic floor, which is the base of our core, and pumping the butt back up, we reactivate the parts of our body that should be holding our torso upright instead of a piece of furniture.
When working with sciatica and lower back pain clients, we not only stretch and strenghten, we also shift how you walk. If you've had that seizing pain or constant aching for a while, I guarantee you've walked weird to protect yourself from feeling it. So, another way to prevent you from having a future episide is to make sure you don't keep walking in a way that supports your body's holding of that pain. Addressing sciatica, and back pain in general, from this progressive approach helps my clients' back pain improve, it also lessens the severity/duration of future episodes In many cases, it helps keep the pain from coming back all together.
