sudden involuntary neck jerks

I am 32 years old male.  I get frequent neck jerks throughout the day for the last three years,  but recently the jerks have increased and i am feeling dull now a days.  Please suggest what my problem is.

Welcome to the neurology forum of medhelp. Thanks for writing in. there could be various causes for these involuntary neck movements that you are having. These could be movement disorders related with hyperkinetic movements of face, neck and tongue due to neuroleptic drugs, , sydenham’s chorea where you may have irregular, abrupt, involuntary movements of neck, limbs,face and trunk and cervical dystonias. These could be tics and tourette syndrome or myoclonus  in response to head or spinal cord injury, stroke, brain tumors, kidney or liver failure.  Please consult  a neurologist at the earliest for detailed evaluation. If you are on any drugs which could be responsible for the jerks, discontinue it  and correct any metabolic derangement. Various anti epileptic drugs are used to treat these disorders like sodium valproate, barbiturates etc. epilepsy per se should also be ruled out. I hope this helps. Please feel free to contact me for any further clarifications.

I am a 23 year old female.Oflate my neck is jerking very minutely. I can feel it. If i try to concentrate on my jerks, i am a getting a feeling of nausea. I did not meet with any accidents and was not administered any drugs prior to this?
Is it because of weakness or do i have any serious problem?
