The creepy crawly sort of uncomfortable feeling that prompts you to have to stretch your legs sounds like classic restless leg. My mom has neuropathy due to breaking her back in three places and her neuropathy feels like her feet are on fire all the time. She has numbness in her legs at times too and a foot drop problem.
The classic restless leg is that making you toss and turn feeling, having to walk or stretch your legs all night. It can be awful. When I was on interferon, I had that feeling throughout my entire body and my rheumie intimated it may have been a very severe flare type feeling (since alpha interferon is the chemical that boosts your immune system in lupus and I was on it also having autoimmunity, which made me very sick), so maybe there is an autoimmune part to restless leg.
I've read that the tingling when you cross your legs or rest your elbow on a table is due to constriction of nerves and is pretty normal, though it has seemed to become more frequent in me as I age. It has to due with nerve compression that you create putting your limb in that position.
I have both restless leg and neuropathy, my dad also has restless leg that seems to get worse when his diabetes is not as well managed. Klonopin works well for my restless leg and also makes my pain meds work better for other problems, but some of the other meds like lyrica, neurontin, and the new meds for restless leg work on neuropathy as well.
I would talk to the docs and get some relief. Its a terrible feeling and worth treating. I think I had it as a child as well and I think my son may have it. Hope you get some treatment soon.
