Yes, it can be..You need to go to see the Dr, especially psychiatrist, it also shows weakness in you. Eat healthy and remain balance in your activities and sleep pattern,there must be some underlying issues,,or you must be feeling some sort of stress in the past. Body tends to respond to the invaders..stress is also a invader..But possible suggestion & diagnosis can be made through a qualified health professional.
Wishes for your health.

I think your palpating because you take too much CNS stimulant like COFFEES, ENERGY DRINKS, COLAS and others. i think you should control your CAFFEINE INTAKE : )

I think that the western diet can contribute to this. If your having heart palpitations and the doctor has ruled out any problems with your heart through various tests then you need to radically improve your lifestyle.

You need to drastically reduce your stress levels and relax. I really think that yoga and breathing can help you relieve stress and invigorate your body. You should also radically overhaul your diet and eat foods rich in alkaline and avoid any acid that could be contributing to this.

Regular exercise is essential for maintaining healthy bodily functions and I would definitely recommend cardiovascular exercise to get the blood flowing.

Hope this web answer helps.
