After ruling out a herniated disc is not causing your sciatic nerve problems, you should look to the pelvis and many times the culprit is the piriformis muscle.
When the piriformis becomes tight or inflamed, it can put pressure on the sciatic nerve and you can get the sensations going down the leg. Symptoms such as numbness, tingling, and sharp shooting pain.
A common mistake I’ve seen on YouTube videos and at different gyms and clinics, is people using a tennis ball, lacrosse ball, or foam rollers to apply pressure to the piriformis muscle in order to relax it.
If your sciatica is caused by piriformis syndrome, applying pressure to an area that’s already compressed will only add more pressure to the sciatic nerve and cause more pain.
What you should do instead, is stretch the muscle causing the problem so that it relaxes and takes pressure off the sciatic nerve. In this video you’ll learn an easy stretch you can do on the floor.
You simply lay on your back with both legs bent. Then cross the painful leg over the good one. And pull the affected leg towards the opposite shoulder and hold that stretch for 30 seconds.
Repeat the stretch as needed.
This will help to relieve the sciatic pain associated with piriformis syndrome.
As with any conditions, there is no quick fix. You have to consistently perform sciatica stretches and exercises to achieve the best results.
