About a month ago I suffered a dizzy spell and felt like i was going to pass out. Since then, daily have these sensations of a rush into my head, a fullness, and my eyes feel like they have a lot of pressure like they want to close, and always with a feeling of lightheartedness. Not to mention, neck and shoulder pain, palpitations, skipped beats. I think something is medically wrong with me, even though its probably stress. I recently had a thallium stress test, EKG, 24 hr halter monitor, EEG, cat scan and MRI...all of which were totally normal...so some doctors say reoccurring headaches and some say panic ,,,what is it,,,,help.. and if it is Panic, can these symptoms happend several times a day?
