The doctors think he is past the worst of it. He is on pain medication because it hurts where the clot is. The blood thinners are working well. There is a chance the clot can move again and cause more trouble, but the doctors don't think it will. This is a common thing for cancer patients, so the hospital is very familiar with this.
He will see a pulmonary (lung...I assume) specialist later today. When the doctor said his lung was damaged, what he meant is that blood supply was temporarily restricted. We don't know at this point how bad the damage is or even if there is permanent damage. In either case, even if some lung tissue dies, the nurse says that won't be a long term problem...people live on one lung, and only part of one of his may be affected.
His attitude is improving, but last night was the low point of his treatment so far. Last night, he didn't care any more. He is heading back toward normal now, but isn't there yet.
This will change his cancer treatment plan. He can't have the treatment to reduce vascular growth for quite a while (whatever that means), but he should be able to do the chemo. He will have to be on a blood thinner for a long time (don't know how long).
If this had to happen, it is a good thing this happened now. It would have been much worse if he had started the medication to stop new blood vessel growth. It would have been worse if he and his Mom had been in the car on the way back to Oklahoma. It would have been worse if they had been on the plane flying home.
I thank God for his work. I thank God for your prayers. I thank God for friends. I woke up friends in Houston at nearly midnight last night, and they went to be with Sherri and Tony.
