Consultant said no exercise - but I only thought to ask him this when in the waiting room, and didn't clarify what this meant. I am on beta-blockers only that are generally manage the symptoms but am feeling a bit jittery today. Wanted to go for a gentle swim - if I don't exercise at all, my muscles get very tight and sore, and my circulation sluggish. Have read on internet though that even this may be a bad idea. Does anyone know?
