On Friday Evening I Noticed A Small Rash On One

Mononucleosis suspected
Detailed Answer:
Hello dear, welcome to 'Ask A Doctor' service.
I read your query and here is my advice.
There are several reasons or diseases that may cause this rash on back, chest.
I think the swollen, hard and tender part behind the ear may be caused by swollen lymph nodes. At this point, I think you may be suffering from mononucleosis.
I would prefer to see a photo of the rash and swollen lymph behind the ear. You can simply upload/attach the pictures to the 'Reports section' of this web page only.
However, you should do a total and differential blood count and a monospot test. Please discuss this with your doctor and proceed further.
This will clarify the situation.
Hope I have answered the question.
Let me know if I can assist you further.
