Hello
@keyboard 010 and welcome
Sorry to hear you are having problems with RLS.
I've got peripheral neuropathy and RLS, the sensation is a sort of crawling, fidgety feeling of something moving over my feet and legs, I've not heard of it affecting the head though. Peripheral nerve damage from higher glucose over time can contribute to restless leg, the peripheral nerves become damaged and cause twitching and the need to keep repositioning the legs.
I've tried various drugs for neuropathy and didn't continue with any of them. I know this is going to sound ridiculous and I did laugh out loud when I was told to try it - the one thing that has worked well for my RLS and leg cramps is a bar of ordinary soap in the bed down by my calves. I have debated whether to actually write this as it sounds like snake oil - but it has worked and calmed my badly damaged legs down. It's on the net if you search restless leg syndrome and soap, it is an Old Wives Tale with maybe a slight explanation about the soap warming and altering leg/nerve chemistry. I am a cynic at heart but was desperate and willing to try for the price of a bar of soap.
I really hope you manage to get some relief from RLS.
