Just agreeing with the many pp who said I do not think your son has an infection. Balanitis just means the glans is irritated & inflamed, which: duh, you could have told them that.
I think it is all 'separation trauma'. The foreskin starts out fused to the glans like a fingernail is fused to your finger- when those connections start to dissolve, and are maybe helped along by the tugging that boys tend to do, it can leave raw spots! It can be really painful, cause swelling, and end in the expulsion of some normal, healthy smegma. As someone else said, I've never heard of smegma blocking the passage of urine before, but combined with the swelling of the tissues, I'm sure it's not out of the realm of possibility. Swelling & pain from separation clears up in a day or 2 without treatment, so even though you used antibiotics, I would not be too quick to believe that they were of help in this case. And yes to watching out for a yeast infection, yo know that can be a side effect of taking abx.
You don't need to clean under there. Even now that it has separated, and not after it's retractable. Just keep wiping the outside if anything gets on it. Baths or showers are both fine; my boys take both. Sometimes the baths are plain water, and sometimes there are bubbles in there (they've never had inflammation from bubbles, but some people do). I have told my retractable 5 yr old that if he retracts in a soapy bath, he needs to rinse with plain water afterward so that soap doesn't stay inside his foreskin and make it hurt. It's really so easy and trouble-free; doctors often seem to create worry for parents where there is none.
*Edit- I didn't see your other thread, and that you've moved onto the 'specialist' now. Apologies for posting here instead of the most up-to-date thread.
