Laryngitis. Days and there is no relief.

Hi on 2nd june i was diagnosed with laryngitis after an ENT doctor did endoscopy of my throat and nose. He gave me medication along with betadine gargle and steam 3 times a day. Even after controling my diet, following the medication and steps told by the doctor i am witnessing no relief. I get headaches, jaw pain, heaviness of nose, throat pain, gas, loose stool, chest pain in the centre bone, diziness and sometime a shock like sentation in the upper abdominal area. I have visited him 3 times, and all the three times he has just told me its because of my sinus issue and laryngitis. So please check the doctor's prescription once to see the medication and suggest should i change my ent doctor or continue with the same as its almost 20 days and there is no relief.
