Well... I don't know about the burping thing.

But I have also had something that I, at least, consider to be restless leg syndrome. (I've never seen a doctor about it.) Actually, over the years, it has spread beyond just my legs so that, nowadays, I feel it pretty-much throughout my body.

I once mentioned it to my psychiatrist. He offered to write me a prescription for Klonopin. He said that would take the feeling away. However I declined. There may be better med's available for RLS. But I don't know what they are. Perhaps other members, here on PC, will. By the way, one thing I do to relieve the restlessness in my legs is to sit cross-legged on our couch as if I were meditating. In my case, at least, it helps a lot.
