I am wondering whether or not the warfarin is the problem, I am only taking lansoprazole with it. 4 days after stopping fragmin injections and taking warfarin my stomach started bloating at night, extreme pains both sides as if I had kidney or gallbladder problems and lower back pain with aching joints. I saw a doctor who prescribed omeprazole and I was having panic attacks and sweats. I stopped taking them and my stomach problems continued and given the lansoprazole, I have an extremely painful and rounded stomach I can feel hard round things on my right under my ribs and my intestines are sore to touch upper and lower, nausea from morning till night. i have enlarged groin lymph nodes now sending pains down my leg. The dvt clinic said I should get my upper abdominal scan brought forward. Is this the warfarin or do I have other things wrong with me? Oh and my hair is falling out for fun so wearing it curly as I darent straighten it. Any advice would be great.
