Ive got tonsillitis but its not getting better my doctor said if it isnt better by tuesday i need to get a blood test but its so sore i cant wait?

Doctor can recheck: Throat pain can be from strep throat infection (antibiotics are needed), mono, a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, a person sees a doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to see about antibiotics). The doctor can swab the throat for a 5-minute test to check for strep.
