sent you a pm. Please see your physician to rule out medical problems. The fact that you say you have never had tics, stuttering and so on says this could and may very well be medical.

Life is stressful from the moment a person is born and the person learns many habits and so on to take care of that, and those things are used through out the persons whole life.

stress is something the person encounters from the day they are born like being cold, too hot, not getting fed right away and so on up into childhood of getting yelled at, meeting new people, school expectations and so on, on into adult hood of job hunting, college, meetings with work or college, and so on. basically life is one huge stress upon another making people grow and become stronger - and their nervious habits automatically follow with - twirling hair, sucking thumb, chewing fingernails, picking at different parts of the body or sores, stuttering, and so on. But all these would be evident throughout the persons whole life. Not just suddenly come on like a cold or the flu.

symptoms of

Headaches -migraines
tics
Stuttering
dizzyness

can mean lots of different things both medical and mental. go to your physician and do all the physical tests so you can rule out -

ear infections
stroke
anneurisms
tumors - benign and or malignant (cancer) related
epileptic seizures
encephalitis
nerve degeneration
parkensons
muscular dystrophy
pinched nerves
Terrettes syndorme

And those are my thinking about the tics only not with the other symptoms too.

Basically by ruling out things the therapists, psychologists, psychiatrists, and medical doctor can find out exactly what type of problem it is be it mental or physical.

I know how easy it is to chalk everything up to being mental. I did that when I started having stomack problems - oh its just nerves, every time I get upset or nervious my stomach hurts, just calm myself down and so on... Luckily my therapist at that time would not let me fall into chalking it up to my mental problems forced me to see my physician.. blood tests came up abnormal,, he requested I go through an endocopy to diagnose an ulcer and treatment for it and the endocopy revieled I had Mucossis Associated Lymphocytic Tissue Lymphoma - a cancer like leukemia that travels the body by way of the lymph nodes. and it had found a home in my stomach lining.

Please don't just assume its mental. if you have never had this happen before at any point in your life then the odds are very high that it can and may be physical.
