Just an update. I took him to the vet about 10 days ago. She took a sample from his head and the spot on his side and said she couldn’t 100% tell but thinks it looks like a bacterial infection on the skin and gave me a cream to put on the spots daily. He’s still looking dull/grayish I have a recheck in about a week and may need to put him on antibiotics. But hopefully the cream gets it done. He does look a bit better tbf.
