Hello Doctor, Of recent I had a blood clot in my left leg. My vascular surgeon put an IVC filter in my right side. I have since been on Coumadin with no ill effects. At the same time I was discovered to have a synovial cyst on my spine. I saw a neurosurgeon for that. When it was discovered I was having excruciating leg pain (before the IVC filter) but the sciatica pain has seemed to resolve and it was stated I may not have to have surgery for that. During all this I was scheduled for a hysterectomy and underwent that surgery successfully . Of late I have been having increasing leg tightness, and feet swelling. My internist said it wasn t vascular, but it is beginning to concern me because of the leg tightness. Any recommendations? I am a female age 67. Ps I do have a fib, but no diabetes. I do watch my salt intake. Does Coumadin cause swelling?
