My boyfriend has cracks in the corner of his mouth on both sides. It isn't cold sores because it never blisters. It burns like a cold sore and hurts when he opens his mouth wide. It normally starts off when he is dehydrated. I put Savlon on regularly as well as moisturiser but it never seems to go away completely.
It will go away for a week or so, and then come back. It gets red and sore, and makes it difficult for him to have a shave. But even when he uses an ordinary razor and shaving cream, it's still difficult to shave because of the sores.
I don't know what causes this but obviously I don't like him being in discomfort. Thanks in advance for any help.
By the way, thanks for all your responses in my previous "yellow tongue" topic. It appears to have gone away for now!
