hello i was in hospital yesterday and my d dimer was 2301, i m a 20 years old girl. i am in the middle of my period (not pregnant) and i am sick for 3 days. My head hurts when i move, i have a fever, dizzyness, whatever i eat goes out in 10 minutes, so i practically haven t eaten for three days, firsty i can t and secondly i don t won t to go to the toilet. At the hospital they checked my veins in head (with some paint and scanning), they checked my liquor with puncture, and they scanned my head and even lungs. They didn t find anything. So they send me home with a virosis, yes it is probably that - as my blood says (crp 114, levkocits 12.5), but still why is my d dimer so high they didn t tell me, can you? what are possibilities?
