Th eonly sure way is to go to a docotr or a lab and get a strep test. It takes abotu 10 minutes and will doagnose strep. Both will cause a sore throat and you could also have a fever with both. But you will definitely have a fever with a strep.
Strep throat is usually accompanied by other symptoms like fever, headache, weakness, and sometimes pain in the ears. Your doctor can perform an easy test to determine whether your sore throat is a symptom of strep throat. It's very important to see a doctor if you have strep throat symptoms as strep infection can become very serious if untreated.
Strep sufferers usually run a fever; might have white spots on the throat and normally don't feel very well at all. A sore throat without strep normally is just sore without a fever. Strep shouldn't be messed with. See a doctor to be sure which is which. Strep can cause several opportunistic really bad illnesses.
To figure out if you should go to the doctor's for a strep test ask these questions: 1) Has my sore throat lasted more than three days? 2) Does anyone close to me have strep? 3) Do I have a high fever and stomach ache as well? Get a test if any answers are yes!
