Developed pulmonary embolism following shoulder surgery. They found clots in my surgery elbow, arm, neck, and both lungs. I ve been on Coumadin and Lovenox injections for 9 days now. INR levels still not in therapeutic range (1.3). Doc doubled the Coumadin/Warfarin to 10mg for the past few days. Yesterday I noticed an itching on the inside of my wrist. Sometimes I see 5 or 6 small red dots, but mostly it s invisible. The area is always damp and noticeably different in temp from rest of my arm. I m concerned reading about Warfarin Rash/Necrosis . I also know that my PCP is going to wave this away as nothing because you can t SEE it. He has not yet demonstrated a knowledgeable grasp of Embolisms and Coumadin protocol so i dont trust him to address this properly. Is this serious enough to pay another visit to the ER tonight?
