Chicken pox - sores mouth/anus?

My 5-year-old son has a bad case of Chicken pox. I've been bathing his skin and also giving him liquid paracetamol. He also has sores in his mouth and anus. Is there anything I can do for these areas or shall they clear up by themselves?

Chicken pox can cause blistering of the mucous membranes in addition to the well-recognised skin rash. The mucous membranes include the anus, the inside of the mouth including the tongue; the conjunctival membrane lining the inside of the eyelids and in the case of females may also include the vagina. The presence of these sores may add to the general discomfort of the condition but is not of serious significance. These additional lesions last for the same duration as the skin rash and they clear up spontaneously. The paracetamol should help to give pain relief as well as reducing fever. If the sores are very uncomfortable there are “over the counter” preparations available at your local pharmacy that should give the child some additional relief. If the sores are very distressing for your child your GP could prescribe a topical lotion or gel, which could be applied to the sores. If the child is reasonably comfortable it is perfectly reasonable to leave the sores alone.
