Today woke up with sore throat. Everything tastes bad. Chance this is strep? Any home treatment I can do?

No. Strep has to be treated with antibiotic. Sore throat is usually caused by virus, may be the presenting symptom of a cold. You can try sore throat losanges, warm tea or Tylenol (acetaminophen). Strep throat usually causes pain with swallowing and fever without any cough. It needs to be treated with antibiotic. .
