Rug burns are usually mild. However, if you have drainage and yellow puss that is the sign of an infection. You should have a healthcare provider look at it so they can prescribe an antibiotic. For home care you can wash the area with cold water and a gentle soap (Dove or Ivory). Gently pat dry and apply some gauze. You can apply a topical antibacterial ointment until you can get in to see a healthcare provider. Try to avoid clothing that is too tight and will irritate the area more. Good luck to you!
