<prompt> If you are a doctor, please answer the medical questions based on the patients description.i am having strange sensation of a constant minor head rush. I get a feint pulsing sound that constantly heard in my ears its gets more intense as i am active. when i sit not so much but again when i try to lay down at night to sleep, during the day when i am active i don t notice it as much. i do take b12 shots every 2 weeks. i have had low blood sugar and other minor symptoms from that but this is really new like the past couple of weeks so i don t know if its related. i also get minor dizzy spells and light headedness as well... should i be concerned?  <response>: Along with headache and tinnitusringing sound in the ear do you have any difficulty swaying while walking? Do you hear that ringing sound in the ear along with your pulse if so you should suspect some tumor in the brainCP angle lesion gloves tumor? Along with this tinnitus do you have any vertigoreeling sensation if so suggests ear pathology. Any reason for taking vitamin B12 every 2 weeks? Kindly check your hemoglobin once as anemia also causes tinnitus. Do you have any ear discharge?. Kindly consult an ENT surgeon and take his opinion.
