I am 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 convinced... 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 months... 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
