I wish you the best with your BCG treatments. I found it to be very uncomfortable when I did the first round of six. You should take advil if you doctors agree prior to the start of the treatment. I remember trying to hold it for the full time and I was so relieved to have it out. Also, I hope you have a good nurse to put the lidocaine ( numbing medicine) prior to inserting the catherer. After a short break with an examination, I resumed the next three rounds. By then, I was able to handle it better with the advil prior to the treatment. After that I had to do another three rounds. I am happy to say there are no further signs of the cancer in the lining. However, I have had spasms and had to try different medicines for that. I will still have follow-ups to see whether everything stays clear. Thanking God for the treatment team. Blessings to all.
