Iam suffering from anxiety and panic disorder but all my pains and sensations are in my head. i feel other sensations through my body but more so in my head. i have had several tests done and everything comes back clean. i am not i feel like i am the only one with the symptoms in my head. i have sharp shooting pains, lots of pressure, dizziness and lightheadedness all the time everyday for the past 3 does anyone else experience this or am i the only one. i constantly feel like i am going to die from a tumor or brain cancer or a brain aneurysm
