My sons had 3 nosebleeds in 24 hrs? He had a temperature fever last Saturday, and said his nose was dry this morning and hexwas picking it which set the first one off. He was ok all day then had another one after school, then we went shopping and he had another one, each lasting 5 mins, we gave him cold tissues and milk to drink. We think it may be dryness so have now wet a tissue with oil and wiped inside the nose.
