Good morning Ladym,
I don't believe we have spoken before, so let me welcome you to the family!
Re your question of the swollen ankle, I have the same problem. I mentioned it to my cardio and he checked both of my ankles. He said if only one ankle is swollen it is due to arthritis. And boy do I have arthritis. OUCH! Having said that, I would suggest when you go for your next dr visit, mention to the dr about the ankle and also your shoulder. In the mean time, try to keep the ankle elevated and I also massage it to reduce the swelling.
My shoulders are a mess from tendonitis, and I have also had bursitis in both shoulders. I wasn't able to move my arms away from my body. I don't know if you are having any problems like that, but I would suggest showing it to the dr. I hope it something that has a simple fix.
I don't know if anyone has directed you to a post called 'Fibro 101'. It is the first post on page 1. There is so much great info there, many of us reread the post frequently.
God bless. Alice.
