What does sore in your throat mean? Can you see blisters in your throat? Or, you mean your throat hurts?
If I had a temperature I would go to the doctor for a throat culture. If it lasts longer than three days I would go to the doctor for a throat culture.
Strep throat has to be treated with antibiotics or you risk rheumative fever or rheumatic heart disease. Strep can still be treated with the old fashioned, inexpensive, penicillins. Strep usually is very painful to swallow, fever, and no congestion, and the throat pain persist more than three days.
A sore throat that is the beginning of a cold usually is painful, but not much trouble swallowing, no fever or very very slight rise in temperature, and the sore throat goes away in about 48 hours, you have a lull in feeling sick, and then 6–12 hours oater you get congested. A cold doesn’t need any treatment, but you can use Chloraceptic spray for your throat pain, and Tylenol or ibuprofen, and later when the congestion starts a decongestant antihistimine combo pill. Ibuprofen can also be used during the day fir overall feeling badly, but you shouldn’t need more than 400mg.
Another cause for a very bad, lasting more than three days, sore throat, is mononucleosis. That is diagnosed with a blood test.
FYI, you can use the throat spray for any of the illnesses that cause throat pain.
