If water flows out a garden hose then electricity flows in the sciatic nerve and down into the leg muscles and nerves.When the sciatic nerve tries to give power to the muscles in the leg, and it gets squeezed the electricity that comes out of the nerve is reduced and you feel pain in the muscles because the muscles are not getting enough power to do their job.
This causes the feeling of tightness around the calf and in the buttock area.
It also makes the sciatic nerve feel like its being pulled almost like a fishing line tensioned when a fisherman attempt to pull up on a heavy fish in the ocean.Reasons for sciatica painTop 3 Three Reasons For Sciatica Pain:Piriformis: The muscle called the piriformis in your buttock is deep inside the butt, and when it does the work of the gluteus maximus which is your number one hip muscle for running, standing up from a chair, or walking then that small muscle in the butt presses on the sciatic nerve and that causes the pain, numbness and heaviness into the calf and leg.Joints of the Lower Back : The Sciatic nerve can also get irritated in the lower back segments.
The lower back needs muscle control to prevent instability.
This means that in order to hold your spine in good position when you are lifting, or bending or even sitting the segments of your spine must be well supported by your core muscles.
When the segments shift due to lack of core stability, there is pressure on the nerve that comes out of the spinal canal.
