Hello. I Am Writing On Behalf Of My Friend. He

Hello.
I am writing on behalf of my friend. He woke up Thursday with a swollen upper lip (left side only) with soreness of his left neck. Thought he might be getting a cold and his throat was mildly sore. Friday he was diffusely sore and spiked temps in the 100-101 range. Chills, aching, fever. Today his upper lip is fine but his lower lip is bumpy/swollen and both sides of his neck are sore. He is running a temp of about 99.5- 101.0, has chills and feels terrible. The migration from upper to lower lip concerns me.
