this is not anxiety. i have the very same thing now for 4 months and am terribly ill. im a young male who developed this symptom along with others. im off balance, weak, total body achiness, weak legs all undiagnosed. but the worst is the nonstop squeezing strangling pressure in my neck and head. its unbearable. its not a headache just pressure and squeezing. it contracts slowly and forcefully with each heart beat. they do not know what is the cause of it. i also have developed trembling internal vibrating and essential tremor at the same time. buzzing in body, neck and ears. its a mystery and my health is out of control.
i know you posted this a long time ago. if you are still having these symptoms, you should go to a doctor immediately and request a MRI. I do not want to scare you, but those are symptoms similar to something i just saw on the news about
brain tumors. My boyfriend has similar symptoms and i am now extremely worried after the story i just saw on my tv. I began searching the web and thats how i came across your post. i immediately felt like i should tell you. i truly hope you do not have anything of the sort. God bless you and i wish you the best. Do not panic, just please see a doctor and request a MRI to make sure you are safe.
