Thank you for your question.

Rashes, and their causes can also be difficult to determine at times, especially as you say your son has not been unwell.

With consideration to his age there is a possibility it may be caused by sweating more, especially if they are involved in sports. The skin perspires more in boys when they start reaching puberty, and particularly where the rash is placed on the upper chest, this may be the case.

Regarding the management of the rash, we would suggest;

  • Keeping the skin clean and dry when possible.
  • Reduce exposure to perfumed products which may irritate the area further
  • Ensure that you monitor the area for increases in size of the rash
  • It may be applicable to apply a medicated cream at night (e.g. Sudocrem) to see if this will help heal the area and reduce the rash
  • Please see your GP if the area gets much larger, starts to become red, inflamed or discharging fluid.

It is possible that the area may be more sensitive to new washing powders, soaps, shower gels, therefore it might be an idea if this continues to possibly look at products for sensitive skin.
