Yvonne, If you haven’t returned to your oncologist or you are no longer on blood thinners since Covid began in 2020, I really urge you to see that doctor or at least your primary care physician very soon. You could be in great risk for the return of DVTs with catastrophic side effects!

Factor V Leiden is an inherited genetic blood clotting disorder where the patient tends to form abnormal blood clots. From my understanding not everyone with Factor V Leiden will have symptoms. But if they have a history of clotting their doctors will prescribe blood thinners to prevent potential life threatening clots. Considering you have an history of DVTs and also have 2 other related clotting disorders, these really do need to be taken very seriously.
Here’s a little information to help you better understand your blood disorders:

There are discussions in Connect with members such as @patientk @piglit @sherohio @susangourdlady @mlemieux and others who have written about living with factor V leiden and related mutations.
