I have RLS. You can go to rls.org and find all sorts of info about your condition.
Hi there.
Unfortunately, the exact real cause of this condition is still not fully elucidated. The lack of sleep that is associated with this condition also has the tendency to aggravate the symptoms and cause even more discomfort and problems.
For severe cases, some doctors would prescribe some form of anti-depressant therapy in the form of trimipramine or other SSRI's. This can help restore sleep, and therefore put a halt on the vicious cycle.
I suggest that you ask your doctors about these group of drugs and see if you are a candidate for such treatment.
Regards.
