Is this Balanitis? So painfull " See images"

Had it for a week and its getting worse and worse, I cant pull foreskin back without being in agony.

I just brought some Canesten thrust cream just incase it is.

Its when I pull forskin back its agony cause its all cut

Yes, that does look like Balanitis.
Keep using Canasten - it can take 10 days to work but I woukd use a little bit 3x a day. But also see a doctor in case it may not be yeast.

Are you sexually active?
Can you expose the head of your penis more easily now you are using the canesten … ?
