What Could Be Causing Vascular Necrosis In Three Joints, Positive ANA, High Inflammatory Markers, And Multiple Chronic Conditions?

The doctors do not know what s wrong with me. They believe it as some sort of autoimmune disorder but they re not sure. I have a vascular necrosis that has collapsed three of my joints; my right knee and both of my ankles. I had surgery on my right knee and they put in a plate and three screws. I just had an MRI of my left ankle today and I m going back to the doctor on Wednesday to see what my surgical options are. While I m there, he got the referral to look at my right ankle, which also has a vascular necrosis and a fracture of the distal end of the tibia. I have positive Ana which is abnormal, and a 4.0 anti nuclear antibody b, which is well over the 0.9 that it is supposed to be under. I have several other chronic conditions. I also have an extremely elevated white blood cell count. I have diabetes, high blood pressure, fibromyalgia, schizoaffective disorder, and a few others which are all being treated as separate issues. All of my inflammatory markers are high. I just want to know what is wrong with me before I end up crippled. I ve already lost three joints and had to quit my job because I can no longer work on my feet on broken bones all day. I m a 35 year old female and a single mother of two young boys and I have no way to pay my bills now because I can t work.
