Internal vibration and muscle mass loss.

Hi! I am constantly suffering from internal body quivering or vibration since last few weeks.I was previously diagnosed with acidity (acid-reflux), so given some tabs like ranitidine,rabeoprazole and finally omeprazole.This drugs seems to be continued only for 5-6 days total.Then, I aborted taking these drugs.Initially when the symptoms started it was like a month ago, I only felt heart fluttering/pounding faster.So, thought as it could be due to acidity and took all those 3 drugs only for limited or dicontiuned period of time.It did fixed my pounding or fluttering heart and burning sensation to some extent.But, here comes the major issue I.e, after that my body began to vibrate internally like a motor engine vibrating inside my body.For no reason, then my body began loosing muscle mass.I can even pull or press my muscles easily as I become so softy and weak like a old age person(Even I can press my bones through my muscles easily).Apart from it I'm suffering from breathing difficulty.
