Dear sir Since one month I am having tingling sensation in the body associated with slight nausea and slight palpitation but no irragular pulse. Tingling starts when I am sitting or standing. Doesn t happen when I m busy or lying supine. This started when I was sitting too much in computer over sometimes more than 10 hours constantly, and was using energy drinks also.habing tachycardiac most of the time but asympatatic. One night I sat on net and developed palpitation but no irragular pulse that disturbed me a lot and that associated with moderate the tingling sensation in the body inside that travelled down to left leg. Like Jacksonian pattern. My bed was very soft and not good. I was sitting over hours in same position I believe that caused issue. In the past I had head trauma with subdural hematoma that evacuated by Burt hole 12 years back with no sequele except when I run I get heavy left leg but no issue upon heaving bicycling. No DM no HTN no IHD no FH.i am 42 active person sexually deprived and un married. Now the intensity of my symptoms markedly decreased possibly sleeping on hard surface with low pillow. But some times I get less intensified symptoms like sweet tingling in the body vanishes immediately towards down and mainly towards left leg. Note sometimes I get right arm numbness for a few seconds to minutes. And I feel chippy (like when you make muscle apart from the king bone)sounds on moving head on either side . I have NO cervical pain at all. Cervical X-ray reveals spasm. Cxr thoracic scoliosis mild. Vit d 12 insufficiency and hit Inj vit d, vit b12 840 slightly higher so I stopped eating meat and dairy items. Please help me.now I stopped using energy drinks and sitting on computer. My vision has issue hypermetropia
