I have similar problems as your husband. For years, I have had very strong, jerking and kicking of my limbs. It's not really RLS, more like uncontrolled spasmodic episodes which I am not aware of unless awakend by my spouse. I also have severe night sweats. I served in Vietnam with the Marine Corps as a Hospital Corpsman 67-68 and while I never remember actually handling agent orange, I know that the entire hill I was on was totally denuded of vegatation which never grew back. I also use an unknown, unmarked chemical which I mixed with diesel fuel and sprayed around the "outhouses" to keep weeds and insects down.
Besides my night time episodes I have joint pain in my shoulders, arms, feet in varying severity most of the time. (no history of injuries and I do not do a physical job)
Could it be Agent Orange? I don't know... but if you ever find some treatment for his jerking at night...let me know. i've tried everything from quinine to anti-anxiety medications. I would be greatful and so would my wife!

My husband also has night sweats, joint pain in his shoulders, and seizures. Started having trouble holding onto things when he came back from Vietnam. He would just drop a cup of hot coffee or bowls of cereal. Said he had no control of this. Wish we knew what this was??

my fiance also jerks before he falls asleep and while he sleeps and he sweats to the point where he wets the sheets he has never had any traumatic experiences in his life could this still be agent orange what should he do and who should he see about this could it come from just daily stress he also goes a really long time without sleeping what should i do
