Hey Binki...I have had the same problem since October. I think the foot pain comes from over-compensating when our hip hurts. For me it is my left foot and my right hip and when I gimp around I put too much stress on my left leg and foot. If you need to walk with a cane for awhile...who cares? Just tell those who might make fun of you that if it's good enough for Hugh Laurie, it's good enough for you! It might just become a new fashion statement!
Hmmm, I really have no idea about that. The only thing I REALLY know about Fibro is that you have to have a specific amount of tender points. As far as my ankle, that actually has nothing to do with fibro, as I was diagnosed with arthritis, PTTD, and osteochondral lesions. But I have no idea why this happened since I never had an injury. Now, I have had swelling a few times also in my left ankle, but that was it. My right ankle is completely deformed now. All my other docs always ask if I have RA, since that does cause joint damage.
But what I can't understand is...I also have diagnosed spine problems, all of which my Rheum knows about. He also diagnosed me with sacroilitis, plus I have hip and spine arthritis as per MRI's, constant disk herniations, etc. But the last time i was at my rheum's, I said I didn't understand why I get such widespread nerve pains and spasms and why it had been killing me to sit, blah, blah...and all he said was it was probably fibro?????!!!!!!!!!!!!! It didn't make any sense. And you know....I've had ankle pain/problems for 18 years or so. It was acting up again and I wanted him to look at it. There were several times he did not look, just said, nahh, don't need to look at it. So one time I just took my sock and shoe off to show him, but he didn't say much. At the time I was going to PT for my spine, actually it was after my spine surgery, I felt like I could finally use the treadmill again, which I did. Well, that caused my ankle to really act up and my PT was so concerned, he did not want me to do that anymore. And he even did an assessment on my ankle on his own; he just took it upon himself to look at it (my PT's are awesome). He then urged me to see a foot doc again and gave me a recommendation. Well, I took his advice, saw the foot doc, and for the first time in my life had it MRI'd and wallllaaaa............such joint, tendon, and ligament damage to it for who knows what reason. He even asked if I had RA. Well, he was the one that sent me for a big foot/ankle brace and it turned out great because it's the only thing over the years that really does take away a lot of the pain. (Except when I get nerve pain from spine radiating to my foot, then it hurts)
Oh, sorry for the long rant here....please just make sure you get yours checked thoroughly and go to different doctors if need be.
