Well, everything I learned Thursday was wrong.
I have a urachal remnent. Basically, it's the tube that connects the bladder to the belly button and in most people hardens and closes. Anyway, mine didn't and has become infected.
The urologist wants me to finish the anti-biotics, go for another CAT scan in 6 weeks and see him again in 8 weeks. But I'm not sure the drugs are working.
That's the news from my end of the world. I appreciate all your prayers and good thoughts.
