My voice is different like scratching. hurts when i talk loud or scream. is it a strep throat? and stuffy nose ,cough ,and little bit of running nose.

URI: Likely just an upper respiratory infection. They are usually caused by viral illness. The treatment is rest, NSAID or acetaminophen as needed for sore throat or fever, increase fluids and possibly salt water gargles/ throat lozenges as needed. If no better in 3-5 days, speak to your doc. Strep can be tested for in office with a swab. It usually has fever, stomach pain and headache as part of it.
