Reaction to orange juice?!?

Maybe my body is just weird but I was wondering if anyone gets sores in their mouth after drinking orange juice?!? I'm racking my brain trying to figure out why I have a sore on the roof my mouth and one on my cheek and all I can think it's from is that one glass of orange juice I had on Sunday! Also I got acne which I never get and that is bothering me too! So, has anyone had this happen to them or am just the only one?!?
