13 year-ols with tiny, not-itchy bumps on face

Hi.  My 13 year-old son had a cold.  A few days later, he developed hundreds of tiny bumps (not itchy) on his forehead which then spread down his nose to his cheeks.  It has not spread past his cheeks.  It's been about a week and they don't appear to be going away.  He seems a little tired, too.  Any ideas as to what may be causing this?  thanks!

Hi,

The rashes could be  due to the viral infection which represents either a reaction to a toxin produced by the organism, damage to the skin by the organism, or an immune response. Exanthems during childhood are very common and in most cases, prior to the rash appearing, patients may have symptoms of general unwellness that include: fever, malaise, loss of appetite or muscular aches and pains.  It is important  that your son rest and drink plenty of  fluids.   If it does not go away, have this evaluated further for proper management and to rule out bacterial causes.
