You absolutely need to insist to take him in and get him checked out. The 2 things could be completely unrelated. I have a doctor that would have just said to bring him in. If he isn't taking liquids, he could become dyhydrated in a day or two. especially with the hot weather. If he is already dehydrated, then he will throw up and not tak liquids becuase of being dyhydrated and need a hydration pack--solves the problem in a matter of hours.
BTW--I just had this situation with my 21 year old daughter, SHe had the flu for weeks and Kaiser Medical just kept telling her that she would be o.k. They were condesending even though she is a pre-nursing student and works at a hospital. She could not take liquids. They told her to go home and sip liquids even though she was throwing everything up and was dyhydrated. I insisted on a hydration pack for her and it relieved the dehydration and allowed her to drink in a matter of 1 hour. She turned the corner immediately after.
hope your son is better--any doubts, take him in.
