I was diagnosed with fibro over a year ago. Just recently, I have noticed a lot of swelling with both legs with the right being worse than the left. I have a lot of leg pain, especially around my knees. I had noticed that it was difficult to bend my right leg and that is when I became aware of the swelling. On bad days when there is more pain and stiffness in my legs, I also have low back pain. It's difficult to get up on my own from sitting. I'm no longer able to sit down in the bathtub and have to be careful what type of chair I sit down in if I'm alone. I cannot stand any pressure on my knees. I have been told by my doctor that I have some arthritis in both knees. I'm just wondering if the swelling is common for fibro. Also do others have low back pain in addition to the leg pain. I've been taking Neurontin, Flexeril and Darvocet, but have been switched to Lyrica which I will begin this coming weekend.
