I have been feeling generally tired, weak. When I lay down, I feel a twitching internally. I have been taking my medication (Daily: Ramipril 10 MG, Atorvastatin Calcium 40 Mg; Vitamin D 50,000 Units), monitoring my blood pressure and food intake. My blood pressure is low in general: 119/73 58 to 82/60 83. My food intake in general: B - cereal/milk/orange juice/hot tea; L - chicken breast/potato/cake/milk; D - ham n cheese/broccoli/apple sauce/milk Snack - soda/crackers/cheese. I go for my yearly check-up in September. What is the twitching and should I go to my doctor sooner?
