My mother is 85 years old and has mixed connective tissue disease, osteoporosis, fibrosis of the lungs, wears a nitro-patch .4mg 12 hours on 12 off. She has been experiencing internal quivering on her entire left side of the body for sometime now , it's worse laying down but, she has it some when she's up and moving around. The worst quivering occurs in the early morning hours before she gets up. Thank-you for your help with this question.
