Harry - I am so sorry to hear about your CHF. Please take it easy and hopefully your new cardio will have some solid answers and help for you! I third the scooter option!!! Glad you decided to stay in school and I know that school must give you some sense of satisfaction!
Almost a year & a half ago, I was told I had between Stage 3 & Stage 4 Congestive Heart Failure. So the doctors in Houston increased the Lasix from 80mg per day to 160mg per day. That change brought me back down to a Stage 2 CHF. The swelling on my legs, ankles, abdomen, SOB, fatigue, are at a very minimum! Off course, I watch my salt intake very diligently which is very important, as I'm sure you know!
I hope that your new cardio is able to make adjustments to your medications that will help minimize your CHF symptoms.
