Warfarin side effects. I now have very round face and lower back, pelvic area joint hurts. Even to touch it. Same answer from Doctor, never heard of it. Plus weight gain. What are we 5 years old? I'm 64 I know my body. Never did this until I went on Warafrin. Was put on Lovenox shots for 6 months. I went bald !!! Doctor didn't believe me until I took off my hat. Still have hard knots and discolor in abdomen. Please don't dismiss me I know what's going on. Why won't he put me on something else?
