my husband has congestive heart failure. He takes warifin, cumadin.....and some other medications to keep his condition in control. He is only 40 yrs. old. We recently noticed his elbow getting very swollen and it looked very bruised. I took him to the hospital... they stuck a needle in his elbow to draw out what they thought was puss....ended up being blood. Right at this very moment they have admitted him due to the fact that the brusing has spread and further up through his arm. he is also telling me that two of his fingers are numb.... what is going on? Please help me
