If you tend to be older, it is usually caused by depletion of hyaluronic acid in synovial fluid within spine. Not all HA is effective. Take the Biocell form (HA + collagen) at 200mg per day. You can take more and all at once. It is important to take this on empty stomach. Most people can feel it working within a week. It takes 6 weeks to heel a herniated disc.
Your spine is like a tire. Loss of HA+collagen will cause tire to deflate. If you try to ride on a flat tire, you know what happens.
If you are younger, the chances are that it is not a HA but depletion problem but just needs some type of pack to help it heal quicker. i forget what they use. I'd still try the HA + collagen. I have cured many peoples disc problems.
