<s>[INST] Hello for the past three weeks I have had a pain in the left back side of my head which is not consistent. It is just a second at various times during the day feels like someone is pulling at the inside of my head. It is located in the back left upper back side of the head. Then on Thanksgiving I had vision problems and I saw a dr and he said it was a migraine. I now developed a pain in my left throat area which is like a jolt. I have this pain in my throat and back of head yet. I have an appointment with my dr on Monday afternoon. Not sure what is going on and I am scared. [/INST] Hello ! Thank you for your question !  I understand your concern. Your troubles seem to be from migraine. The vision problems and throat can go with migraine attacks. The unilateral feature, the throbbing feature of your pain go with migraine too. I would like to know more about your age, lifestyle, past medical history. Although I would also recommend you a brain CT scan o MRI to rule out any other disorders causing these symptoms. Wish to have been helpful! Thank you for using Chat Doctor! Best wishes,  </s>
