Maybe: It is possible, depending on location of the bumps/rash. Areas under clothing or heavy perspiration are potential sites for such rashes. If on outside skin areas where sunscreen was applied, may be assoicated with contact allergy to the sun lotion or its preservatives contained. Do not scratch them. You may try use of 1% hydrocortizone cream (cortaid) applied 2-3 times a day... No scratching.

Not likely: It is likely the sunscreen had an ingredient that when exposed to sun caused a reaction called "photo sensitivity".
