Hi everyone, Ever since my initial sroke in 2011, and two TIAs in 2012 - after which I was diagnosed with APS and am now on warfarin - I have these periods or bouts of light headedness. Its not dizziness, just an uncomfortable sensation of feeling light headed. I get quite anxious when these start. My GP and haematologist tell me that I have post traumatic stress disorder and that these are probably being triggered by anxiety - not an after effect of the warfarin or an outcome of having APS. My doctors want me to see a psychiatrist. My haematologist tells me that he does not beleive that the warfarin is causing these episodes. Have any of you had similar experiences? Thanks.
