what could cause a bright red raised skin infection around the neck and upper chest. It looks like impetigo but the patient is a 65 year old man. There has been no change in detergents, skin products, etc. It erupted very quickly - in a matter of about 2 hours.
Hi, The raised akin rash is commonly due to hives (urticaria) which occurs in a short period of time.  As you have mentioned it as a skin infection it could be erysipelas. Treatment varies for both the conditions.  Urticaria is usually managed with antihistamines and erysipelas is managed with antibiotics.  I request you to consult your Dermatologist to confirm the diagnosis and to initiate the treatment. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
