Fluttering or vibration while movement.

I don't understand, though many doctors said I'm suffering from vitamin deficiencies like B12, D, etc. But, is it too related while I move my body.Means, is the vibration or tremors(sometimes, these tremors or vibrations are like the vibrations someone have when he or she excites, fears or something like that). These tremors seems to develop internally the most.I even can notice those tremors or fluttering happening with my chests,abdomen and legs too.The thing is, I can't control these kind of vibrations or tremors or shakiness.It only and only can be stopped or shutted down while I'm in deep sleep, otherwise not.Maybe due this I can't properly see or have a little blurry view and have muscle looseness.Doctors, please it's an request to evaluate and deal with this kind of problem ASAP.
