Can a non occlusive thrombus keep clotting while taking xarelto? achy pains and pulled muscle feelings on left side of body and leg where clot is?

Clot retraction: A clot under treatment can grow if there is a failure of treatment. There are indeed some people who still can clot under any of our treatments, not one treatment is 100% effective in 100% of people. The pain may be just a continuation of what was there to start with and may not completely go away simply with clot resolution. Talk to your doctor for treatment.
