My son was circumscised at 11 months 3 months ago now , as he is chubby, we have had to pull the skin back to clean it still, once pulled back you can see that there is a bit of raw skin on the side of the rim of the bellend that was catching apparently, so our dr gave us kyjelly, it was becoming more comfortable for him but now that part of his penis on the side of the rim is quite red and swollen - the penis itself isn't swollen tho- can I use savlon cream on it?
