Hi, Rebecca, and welcome! I'm glad you found us and joined in. Is there any way you can get out of bed and walk? Staying in bed will make you stiff as a board with fibro and will make the pain worse. If it's not the heart failure that is keeping you in bed, then you should start walking. Be sure to talk to your doctor first, though.
Be sure to check out the Fibro 101 thread...the second thread on the forum. There are links to good information about fibro there and you will learn a lot. There are some good stretching exercises in Fibro 101, too, and you can do these sitting down. That might help you some, but gentle exercise would help more.,,like walking and swimming. Who knows? It might help with your heart, too.
I'm sorry you are going through all of this. I truly hope the doctors can help you with fibro and help your heart condition, too. You are far too young to be bedridden. You have a lot of living to do. If you can get out of bed and start moving, that would be wonderful.
I'm happy that you are here and don't hesitate to ask questions. We are here to help you. I hope to hear more from you soon.
