Update:
This Saturday I was at the hospital with Dad when the oncologist came in. Dad has cancer...Hodgkins Lymphoma.
It was sort of a good bad news situation. The Dr. said it is probably the cause of everything that is going on and the reason why he wasn't getting better. Now that we know what it is, treatment can begin immediatley and he was confident we could see positive improvement immediatley.
Thank you for all the thoughts and prayers to date, they have helped so keep them coming as Dad's treatment begins.
