Multiple ailments. What should be done?

I am having various ailments from few days which are not going away and making me panic. A week ago, suddenly i felt sharp pain in ny head and the same day i lost control, sweated suddenly and felt short of breath with palpitations in my heart. From that day, i am feeling some choking feeling in my throat and pain in my ear and jaw. I referred to ENT for the same, he told i have no visible problem in my ear , neither throat. Only medicine he prescribed me was TRIKA-SR(for 5days) for stress as i am under deep stress from few days as my maternal grandmother got expired and i was so much close to her. After taking the medicine, i am relieved from the choking feeling but still having sharp pains in my ear, head and jaw(which comes & goes) along with mild dizziness. I am a migraine patient too. Please tell me what could be the cause and what should be done?
