deep vein thrombosis
"I had two instance of DVT getting to my lungs. Almost killed me. I was on warfarin the first time for 6 months with no side effects. I have been taking xeralto 20 mg for about a month now. I am having insomnia, upset stomach, and occasional muscle cramping in calves and ankles. However, I do not have to go the doctor once a month to have blood tests and I do not have to manage my eating habits so closely. So far I am a fan, albeit a sleepy one."
