Thank you for sharing. Have you shared these symptoms with your medical team? That is always the first place that we recommend you go for guidance on symptoms. Have you asked them? For the right arm pain, I've had that as well and I was told that right arm pain is not typically cardiac related, but never say never!!! Does the pain coincide with chest pain? These are all important pieces of information for your medical team. Also, as far as muscle aches, I can say that I have those as well, and potassium and magnesium supplements have helped. Are you on diuretics' as well? I hope this helps! Morgan (heart-failure.net Moderator)
