Hello--my 22 year old son was to the doctor friday and was tested for influenza b. It was positive. He had the chills, fever and became a bit dehydrated. He is feeling much better today but an oval shape red rash has appeared on theback of his right leg behind his knee. No blisters, but it feels warm to the touch. Is this from the flu? Thanks for your time, nancy
Hello, Viral fever usually presents with symmetrical extensive rash. Unilateral single rash is not usually due to viral infection. It could be a bruise or a purpura. So, I would recommend you to consult your Dermatologist and to follow his instructions. Hope I have answered your query. Let me know if I can assist you further.
