I was diagnosed with APS 2 years ago and I am taking Warfarin 4 mg and a 81 mg ASA daily. I live in Central Texas and have had great difficulty finding a physician who knows how to treat APS symptoms . I have a appointment with a Rheumatologist who wants a Cardiolipin AB ran, from what I have read on the test it is not accurate if you are taking Coumadin. I would be very uneasy about stopping it for any length of time and my symptoms worsening or having a TIA. Among many other symptoms I have somewhat localized muscle pain , tightening and weakness in my left inner deltoid for about 3 months. Is it common to have muscle pain in one area for a length of time ? Since diagnosis I have had very heavy feeling legs, like walking through sludge on a daily basis. Also have tingling in my face every day in different areas , I wasn't sure if this might be from Coumadin or the APS. Any advice would be greatly appreciated.
