Ok so i think i may have strep throat how serious is it an what's the best treatment ..reward for best answer.

Complications: Untreated strep can be followed by antibodies that attack your heart/kidney or brain. Rheumatic fever describes the systemic onset of this reaction where the patient is fairly ill & the heart & heart valves are inflamed. If the kidneys are attacked they can weaken & blood pressure goes up.If the brain is attacked you can develop a movement problem.Sometimes the tonsils just abscess & u risk dying.
