The good part is, Don's eyesight got better every day, it is now back to normal. That means that it's not that rare condition associated with melanoma they thought it might be and it's a reaction to the drug.
The bad part is, on Tuesday we had just arrived at our landlord's new house for a cook out when Don suddenly had to go to the bathroom. With no warning at all, he had diarrhea but it was all blood. So off to the hospital we went again. His hemoglobin was fine, so he wasn't losing any blood. His white blood count was high, showing signs of an infection. They did a CT scan and found it was not more cancer. They wanted to watch him for 23 hours to make sure he didn't do it again. They didn't want to give him a colonoscopy since the colon was inflamed and it would be too easy to end up with a perforation. His oncologist came in and could not believe all the side effects he was getting. He agreed that he was a patient he will always remember.
The other good part, when they did the CT scan they found that the tumors on the liver had shrunk. The problem is that so far he has been allergic to everything. They are giving him 10 days then they will try another. Finally, something good.
