my uncle had a bleeding ulcer which caused him to go into the hospital for a 10 pint blood tranfusion. this occurred over two weeks ago. he has since been diagnosed with a blood clot in his leg which they can not put him on a blood thinner because his blood is too thin. he is having trouble getting out of bed now due to dizziness. my question is what would cause the lightheadedness? thank you
