I am a 66 year old male. I am having sensations of bugs crawling on legs (actually feels like on the hair of my legs). There is one spot on the right hand side of my right knee, that I feel it on frequently (once or twice each night) often when I am sitting at my desk. It started about 5 years ago at my desk in the evening. We've since moved to a new home and it still happens more often at my desk, but also when sitting in our tv room. There is never anything there, and it feels like a fly not a tiny almost invisible bug. Most often it happens when I have shorts on, but sometimes even when I have pants on, but almost always from my knees down. I also get a less frequent spasm in one or the other leg. Almost always while in bed. I feel it coming (every minute or so) and I try to suppress it, but I can not. Usually I get 20 or 30 spasms and it stops on its own. Recent sleep study nurse told me it happened throughout the night. I thought possibly these two things might be related.
