Cellulitis?

Hi guys, I’m on vacay with my boyfriend out of the USA. He does jui jitsu a lot and before we left he had what we thought was ring worm (super common for wrestlers) and doctors gave him a cream for it. Over the span of a few days, it’s worsened. Doubled in size now, very itchy, burns on perimeter, red, yellow puss comes from it, his bottom foot got swollen. We went to urgent care here and they took pics for the dermatologist to look at it and said they would email us in 24 hours with the results and with medicine for it. Afterwards, his USA doctor called him and said he wants us to go somewhere again to make sure this isn’t cellulitis. I’ve never heard of that until I started researching and it seems very scary that needs treatment immediately. Please any advise will help, does this look like cellulitis? Does anyone know what we can do to prevent it from worsening before we get the results from this doctor in 24 hours? This pic was taken after he showered so you can’t see the yellow puss.

I know I’m freaking out, but I trust the healthcare system is good here and they were really thorough with asking questions before sending this to a dermatologist.

Please give me your thoughts. We are here until the 19th but will be back in USA on 20th.
