I woke up yesterday and my bellybutton felt very wet, on inspection it's turned bright angry red/pink on the inside and seems to be a bit crusty and oozy and sore to the touch, it's quite deep as far as belly buttons do but I shower everyday and am clean so I'm a bit miffed because this seems like something someone who is a bit sweaty and unwashed would get. Can I sort it at home or get something OTC or will it go away?
