Hello and thank you for sending your question.
You have indicated that despite the fact you are on anticoagulation you have significant pain in your arms. The pain could possibly be related to some musculoskeletal problems such as a pinched nerve
but in light of your history it is important that your doctor rule out additional blood clots
It is theoretically possible to have a blood clot even if the blood is thinned with Coumadin
. If that is the case the Coumadin needs to be changed to an alternative anticoagulants.
While it is unlikely that you have a blood clot it is important that you review this with your doctor so that appropriate diagnostic testing can be done.
Thanks again for sending your question.
