dddennis13 posted a question in VA Disability Compensation Benefits Claims Research ForumHi I reopening my case since I've been told there is a causal relationship between AO and deep vein thrombosis. does anyone have an verification of this? I'm also told there is a causal relationship between heart disease and lung disease. Can anyone tell me what sort of disease is covered? LAST ONE I have numbness in my fingers and toes. Is that related? Thank you. I am very grateful for information.
