I have a mysterious problem discovered when I kissed my wife immediately after she got iching in her lips and cause swelling in her lips although I had brushed my teeth before that. May I know what may be the reason? This has happened 2-3 times. I am very much worried. Please help. Another problem is that - after chewing the vegitables if I throw out. It turns into red. Means when I bring out form my mouth any green vegetables gradually it turns into red. Please advice.
