I Have Been On Antibiotics Since Last Wednesday For Probable

I have been on antibiotics since last Wednesday for probable sinus infection and swollen glands, clear nasal passage and no drainage, 5 days in to the antibiotics I started running a fever, I can keep in down in the 90 decree taking tylenol every 4 hours. My glands are swealing again and are very sore. I started itching, first in my joints now all over and I am now one big hive, so I added benadryl to the mix. My daughter thinks I need to be seen. I have an appointment for Friday, not sure if I should just keep that or go to urgent care.
