I have what I call twingling, which is a mixture of twitching, tingly, prickling, sometimes burning in my legs, usually when I am sitting down or lying down in bed. They sometimes feel like tiny electric shocks sometimes. I've had this for ten years. I don't have any symptoms in my feet or upper limbs, apart from the odd twitch. I can walk for miles and no symptoms but as soon as I sit down the horrible twingling starts.
I had all the nerve conduction studies 10 years ago and was told I may have benign fasciculation syndrome. I managed to live with this for all these years, after the anxiety of some awful diagnosis had subsided, but now they are back worse than ever. I cannot sit down or lie down without the above symptoms coming on almost instantly. I am wondering if I have a peripheral neuropathy rather than BFS. It really is a problem even though I only have it in my legs....mostly.
