Hi from Norway 😀. This is my first post here. I got APS and PE in both lungs this summer and have been using Xarelto since that happened. The last Month thow, I have felt light headache and dizzines, every day, and this weekend I had a short TIA. The doctor want me to change to wafarin instead. I am worried because of the risk of utstabile INR, and will this help with the headaches or is it the APS ?
