I was diagnosed 16 years ago with portal vein thrombosis which is a blood clot deep in the liver. Taking Coumadin or warfarin is not an option for me it is a necessity to live. I experienced headaches and depression early on which I did not connect to the drug because of the trauma I had been through. The symptoms have come on over the years and seem to be worsening. I am experiencing severe joint and muscle pain, cramps in my legs and hands, extreme weight gain, severe water retention ( I take 3 kinds of water pills a day), extreme fatigue, insomnia, heart valve problems, memory loss and have recently found out I have developed severe osteoporosis in the last 10 months. I have recently undergone tests for auto immune disease, lupus and rheumatoid arthritis which all came back negative. I am 42 and feel like I'm 72. I keep asking the doctors if these symptoms are related to the long term use of the drug and they say it is unlikely. I currently take pain killers to manage the pain so that I can function daily. I take 5 mg and 7 1/2 mg alternately and keep my INR around 3.0 to 3.2 and am very stable. After reading these postings I am even more convinced it is the drug. Is there anyone out there that has been these drugs as long as I have and if so, what are your side effects?
