I have throbbings such as quivers that last for some seconds in different muscles also I can see it with eyes when flesh starts to quiver for seconds.?

Muscle twitching. Muscle twitching is very common and can be related to dehydration, electrolyte imbalances, medications, and other problems. Try increasing water intake and starting a daily multivitamin. If no improvment, see a regular doctor.
Quivering muscles. We need more information to determine what is exactly going on here. If it occurs after exercise, then it is quite normal. If not it could be a sign of several other conditions associated with endocrine imbalance or dysfuntion, electrolyte abnormalities, neurologic disorders, etc see your primary care physcian for an evaluation.
