BCNA has a great booklet on exercise that you could ring up and ask to have it posted out to you.I had all my lymph nodes removed in 2003 and I don't really get lymphoedema.Sometimes if I overdo it in the garden or sweeping/mopping the floors,my arm might feel alittle heavy or just above my armpit gets abit puffy.I usually do a gentle massage of my arm and underarm. It's trial and error and really you can do what you like,although I wouldn't go lifting heavy furniture(I've done that!).Don't get your arm sunburnt,don't have blood pressure taken or blood taken on the"bad"arm. I do pilates and have no trouble.I don't know what hot yoga involves but perhaps you could start off slowly, once a week till you see how you manage.Good luck with it.
