Hi All,
Wondering if anyone has had a similar experience to me? My CIDP was diagnosed in September 2013. Main symptoms were limb heaviness and weakness, falls, dropping things, visual changes, continence issues, arthralgic pain in my arms. After a 5 day induction of IVig in November I continue to have fortnightly infusions.
Coincidentally in August 2013 I started limping to protect my right foot with no identifiable injury precipitating it. An MRI showed a recent fracture in my ankle, and avascular necrosis in which bone tissue starts dying off after its blood supply is compromised. The falls were all 8 - 10 months before any pain arose. Diagnosis was later amended to bone marrow oedema syndrome in which the bone becomes abnormal and osteoporotic leading to insufficiency (of bone) fractures. It is self resolving over 3 -9 months with no treatment other than protected mobility.
A walking boot, crutches and occasional wheel chair allowed my ankle to heal over 6 months but 9 months later I remain largely immobile because as my ankle became stronger, my right knee developed the same problem The diagnosis then became migratory bone marrow oedema syndrome. Then as my right knee became stronger and I was about to return to work, my left hip and knee developed what seems to be the same problem, to be clarified by MRIs later this month.
As each new joint has flared up I have experienced a 10 day flare up of the CIDP symptoms and I am convinced the conditions are linked.
Research got me to the point of understanding that a particular protein that we make in bone and kidneys (osteopontin) becomes elevated in both conditions (and in multiple sclerosis, rheumatoid arthritis and some other conditions). One study proposed that manipulating osteopontin levels might relieve symptoms. This led me to finding and speaking to a medical researcher in the relatively new field of osteo-immunology who agrees that bone health can also be affected by inflammatory neuropathies but so far the research is in early stages and not linked to particular conditions and has no clinical applications.
While my neurologist and orthopaedic doctor are sympathetic they don't agree that the conditions are linked - their take is that I have two rare but unconnected conditions. I have now been referred to a rheumatologist who I will see for the first time in mid May and am hopeful of gaining a better understanding.
All of this continues to seriously impact my mobility, work capacity, financial and general well being. I'm thinking that although the bone marrow oedema syndrome is rare as is CIDP, it is unlikely that I am the only one affected in this way.
Has anyone else's mobility problems been related to bones rather than motor weakness?
Thank you for wading through my story.
