My father is 83 and generally in good health. He was diagnosed with bladder cancer and was successfully treated with the BCG protocol of Dr. Lamm. After his first follow-up BCG treatment course, he experienced more fatigue and flu-like symptoms than normal, and an low-grade fever. In the course of a few days he broke out in a large rash that was misdiagnosed as a fungal infection. After things got worse he was admitted to the ER the rash was easily recognized as a shingles outbreak on the S2-S3 dermatome area. He was then given a course of Acyclovir to take. Now he is having severe bladder spasms/pain, especially at night. My question is this - is the shingles outbreak related to the bladder spasms/pain, or is the most recent BCG course most likely the cause? Also, if the shingles and bladder trouble are causally related, what should be done to minimize the trouble now, and what is the most likely time-frame for things to resolve (or progress)? Thank you for any guidance you can offer -
