I'm new to all of this and really struggling to understand and manage my anxiety. I was diagnosed with a DVT and PE 10 weeks ago and was placed on Warfarin. At the time they said it was unprovoked but I've subsequently had a positive result for APS. A month into taking Warfarin, I started to get nausea, feeling weak and worst of all shivers that come and go. I also get up to urinate a lot at night (but this I have had on and off for years.) Does any of the above sound like common symptoms for APS, Warfarin or some other issue? Doctors think its anxiety.
