Head jerking

[Loo59]

I experience continual gentle head jerks noticing especially when concentrating on eg. watching TV, talking to someone in my job or beingsitting in meetings.  Jerks don't happen while I'm asleep.  I do need to relax position my neck so that it is relaxed in a good position.  I sleep on a towel that I can shape to relax my neck.  Often I have to hold my head still with my hand under my chin to control the head jerking.      
I am 51y and have had this happening to me for 2 years.  It's gradually getting worse.  I used to suffer from migranes for years.  I had a mitral valve replacement in 2008, since I have been getting migranes often but most often without pain.  Also my body at times feels slow, out of energy and stiff.  I also suffer from lower back pain at times. Also my daughter who is 26 has gentle head jerking but her head goes from side to side unlike my head jerks down and up.      
I am concerned about this condition getting worse and would love to know why the jerking is happening and what should I do.

my son age (5) has been throwing his head back fifteen to twenty times within a three min period every like 30 to 35 min, I took him to the doctor but he did nothing told me his adhd could be the cause, never gave him a x-ray nor did anything about this told me to take him to center stone which is only for his adhd, said he was probably doing it for attention, but I know he is NOT doing it for attention I have been recording him doing this, it gets worse when he watches tv or playing a game!!! I need answers this is not normal for a child

Headaches, heart muscle problems, fatigue, muscle stiffness, muscle pain, tics, twitches, spasms, etc. can be caused by a magnesium deficiency.  Magnesium is essential to healthy muscle and nerve function and relaxation.

Do some google research on magnesium deficiency and you will find a wealth of information.

Some of the safer and more effective forms of magnesium include: Taurate, Glycinate, and Citrate (latter can be laxitative -- take with food).
