** Thanks for contacting with your health concern 1. As you are on blood thinners thus DVT [deep vein thrombosis] has to be immediately excluded as there is severe pain in the calf muscle, so seek immediate medical intervention [vascular surgeon opinion] or visit an ER. 2. since there is period of 5 months, thus it is important to know that if patient leads a sedentary or inactive lifestyle he is prone to formation of blood clots which can result in embolism [watch closely for any new chest pain with difficulty breathing, and rapid heart rate] 3. Monitor your INR [international normalized ratio] since higher values carry the risk of bleeding and subnormal values carry an increased risk for repeated thrombosis.
