Can MPNs cause swelling in your ankles and feet?
Yes, MPNs can cause swelling in your ankles and feet, though this isn't one of the most common symptoms. Swelling may occur due to several MPN-related factors.
Blood clots are a significant concern with MPNs, particularly deep vein thrombosis, which can cause leg swelling. High red blood cell levels, abnormal platelets, or abnormal white blood cells increase the risk of clotting complications.
Additionally, some MPN treatments can affect your skin and extremities. Hydroxyurea, a common MPN medication, may cause ulcers on the ankles or legs as a side effect.
Your fingers or toes may also feel cold and turn blue due to circulation issues related to MPNs.
If you're experiencing new or worsening swelling in your ankles and feet, it's important to discuss this with your healthcare team. They can determine whether it's related to your MPN, a potential blood clot, medication side effects, or another cause that needs attention.
