I am experiencing a lot of widespread pain, especially between my shoulders, also numbness and tingling in my back, fatigue and losing sleep. Also, have a lot of inflammation in my eye. I had blood work done to check for autoimmune disease because of the pain and the inflammation but it came back negative. Can I still have an autoimmune disease with negative blood work? I have been diagnosed with a Chairi Malformation 1 but the Neurosurgeon said it wasn’t bad enough for surgery and that my symptoms did not line up with the Chairi.
