I am a 55 year old female and had APS autoantibodies detected in 2 different blood tests 2017 and 2019 but never officially diagnosed with APS for some reason. I also have small fiber neuropathy and autoimmune Hashimoto’s thyroiditis plus alopecia areata. After getting the COVID vaccines in 2021, I had shortness of breath, difficulty breathing, and chest pain like I was having a heart attack at least 3 different times. This happened over 3-4 months after the 2nd vaccine and EKGs in 2022 showed an old infarct! Later I was diagnosed with sleep apnea since I was having a hard time breathing overnight. Have you ever been tested/diagnosed with sleep apnea since your APS diagnosis and pulmonary embolism? Also, has your doctor considered adjusting your APS medications? You may want to check your symptoms against the Xarelto side effects. Did your neurologist test your for small fiber neuropathy via a skin punch biopsy? This can affect your heart, lungs and blood vessels.
