It's on and off one her, she had by-pass surgery already and on insulin – she is scared but don't trust the doctors because of so many mistakes and ommission on her record – she changed doctors because of that – could she be in danger right now? She has an elevated cholesterol too – but not that much -and she is taking baby aspirin already and she runs and exercise plus she is watchful of her diet. It's the numbness on her left 3 fingers that she is concern that has been numbing on and off since the by-pass surgery only this past month is more intense. Please help her. thanks.
