I am 60. 1 week ago I lost my voice and had big pain in

My name is***** am 60. 1 week ago I lost my voice and had big pain in throat. During this time I didn't have any fever (36.2-36.3). After 3 days look like abscesses in throat were opened and came out pus. I was thinking, that sickness is over, but tomorrow evening I had temperature 37.9. I didn't drink any medicine and temperature now 37.3.I feel myself very week. Can I go to work tomorrow? Or I need to go to hospital (because my GP don't have any appointment). Thank you for the answer

JA: Got it. Have you used anything besides Chloraseptic for this?
Customer: no
JA: Thank you so much for your time. Finally, is there anything else in your medical history you think the Doctor should know?
