CHQ: SUBJECT: physical activity
  MESSAGE: I am a woman aged 59 and had triple heart bypass in 2010. I am 5' 1" and almost 14st in weight so fairly overweight. And I have very swollen ankles which ive had for probably at least 20 years. Diuretics dont seem to solve it. Ive had to take on part time work now as the government say i have to as im under pension age, working 4 hours a day, and it involves standing as its shop work. Should i really avoid this type of work as it means so much standing? Im very unfit, too weak and breathless to climb stairs. I suffer regular severe back ache standing for a time and my legs ache badly. I cant climb stairs as i get breathless and my legs are too weak. I dont smoke and dont drink alcohol frequently.
