Just to let the people who asked me to post how I got on at the GPs with my restless legs and twitching.
The dr said it is possible to treat, as I think someone mentioned you have to take a valium based medicine, or alternatively drugs developed for parkinsons. In my case she has decided to send my to neurology as I have other neuro symptoms so I have to wait for treatment until they have seen me.
But main point: this IS a symptom that is treatable.
