They determined today that Cara's head pain is not caused by a clot, so that is good. The bad thing is that right now they still are not sure what it is. It could be a migraine, but they want to still keep her a little longer to monitor her more. She is still pretty weak. We went to Madison to see her and pick up Dick to bring back home. We are hoping she gets out of the hospital tomorrow, but most importantly, we are hoping that there is a diagnosis. Keep your fingers crossed! Where is Dr. House when you need him?
