Strep or cold? symptoms: sore throat 5 days, ear pressure, sinus headache, cough today and yesterday. fever for 3 days.

Needs diagnosis: The only 'definitive' way to tell is by obtaining the right testing - and in this case, a throat culture would determine if you had Strep or not. Since you have fever and ongoing symptoms, I strongly encourage you to get tested - this will help shape the treatment plan, and lead to your improvement. In the meantime, chicken soup (or pho), plenty of rest and ibuprofen for symptoms may help.
