Unexpected trip to the hospital

So Dad has been enjoying himself these last several days prior to the big day and event coming up. Today, Dad said we woke up with some chest pain because he was sleeping on his side so his back was hurting. Then they went to breakfast and church. After church they hit a movie. On the way down, Dad started to feel light headed, so he sat down to catch his breath. Then they got him home to eat something, check his blood pressure and his blood sugar. He still wasn't feeling quite himself so he went to lie down, when he noticed he was feeling a bit warm. When he checked his temperature, it was 101. He called his oncologist who told him to go to the hospital to get a chest xray. He might have to be admitted tonight instead of tomorrow. By the time they got their things gathered, his temperature was down to 100. With his fever, there is a good chance he will not be able to have chemo tomorrow. I will keep you updated as I get more information.
