Advice?

My son is 9 months omd and since he was 7 almost 8 months hes had a red ring around the base of his penis hes seen his oedistrician prescribed aome cream it went away and then came back and now weve tried diaper rash cream and baby powder which usually worked but now it's not doing snything and its gonna worse its pretty much all the way around his penis.

Anyone know anything to help?

I don't think I can pist pucs without my post getting deleted but he is uncircumcised we clean him when he pees or poops and its not the hear or anything its the base of it.

Went to a different dr he didn't even look at it jsut said poop is acidic and it can cause redness.

I can not find any dr that will take us seriously about anything when it.comes to our son.

Im seriously considering taking him to the er about it he fights us a lot now when we go to change his diaper soemtimes he doesn't see to be in pain other times he does.
