I have some questions to ask. About 10 months ago I was diagnosed with dvt I took medicines for 3 months and I was clear from it. Now I went to doctor as my leg was a bit swollen gp sent me to hospital to do x-ray and a blood test. My blood test was fine but they saw something on x ray and they told that I got dvt again. Is it possible for blood test to be normal and scan to show that there is. Just I didn't trust the doctor who was doing scan for me.
