When I eat most things now, my cheeks and nose go red, sometimes fiercely so. What's causing this?

Flushing is part of the activity of the autonomic nervous system - the one that controls the circulation in that area of skin and the start of the digestive process. Yours seems to be more sensitive than most. If it really is embarrassing for you, your doctor may be able to help with something to quieten the reaction. If it isn't, leave things be. The flushing should settle. If it makes you feel ill, that's different, and you should tell your doctor.

My seven-year-old son has had warts - mainly on his knees and in between his toes - for three years. A large clump was removed by freezing at the hospital, where he was advised that the ones between his toes can't be removed this way. The doctor at the hospital says there is nothing that can be done. He has a very good diet, as well as omega-3 fish concentrate with vitamins A, C, D and E most days. Are there any herbal supplements that are safe for him to take?

Warts always disappear in the end (they are a virus infection that the immune system eventually defeats), and some specialists advise leaving them alone. I wonder why you are giving him so many supplements? A healthy child who eats normally doesn't need them. Ask your doctor for a long appointment to discuss your son's skin problems, and the supplements you are giving him.
