What causes itchy rashes on the neck and arms?
Patient: Hello my name is jacqueline, I had a question I began having this rash on my back on my neck it happened before going to bed I scratched myself and ignored it and went to bed. The next morning I woke up and realised the rash had spread to my ears and my ears got a little swollen and they were so itchy and hot. An hour later it had spread all over my face and its been like this for a week already and its going to my shoulders and my face is fool of the rash. I just want to know whats wrong with me help me please. Doctor: Hi,  The rash could be erysipelas which is a bacterial infection of skin. It is usually associated with fever. You can initially apply a topical antibacterial cream. But, ideally, you should visit your Dermatologist immediately, to confirm the diagnosis and to prevent worst outcomes.  Hope I have answered your query. Let me know if I can assist you further.
