The fluid in the cyst can put pressure on the nerve inside and on the adjacent nerve roots and cause debilitating symptoms.They can occur anywhere along the spine where there are nerve roots. They are most prevalent in the sacrum or base of the spine.he fluid in the cyst can put pressure on the nerve inside and on the adjacent nerve roots and cause debilitating symptoms.

To clean mineral deposits in tea kettles, you can use calcium, lime, and rust remover or distilled vinegar.
For tough-to-remove rust stains (and as a last resort), cover the stain with table salt. Take half of a lemon and squeeze the juice over the salt. Scrub the salt/lemon mixture with a clean cloth or a nylon sponge. If the stain still doesn't come up, leave the paste-mixture on the stain for an hour or so.
