I am a new registered member and I am excited to talk to someone else who is going through these awful problems. Quick background, I am a professional with a wonderful supportive family. I have lots of friends and am well liked. People see me as a leader and a mentor.I have a wonderful life and have always had. I do not mean to pat myself on the back but from what I have read regarding panic and anxiety I do not necessarily fit into the mold. I have been dealing with anxiety symptoms for 4 years. I do not know why this happened to me. I have a masters degree in biology with a concnentration in biochemistry. Because of this I am not convinced that what I am experiencing is panic and not an underlying physiological problem. I have been tested for everything under the sun (god bless my doctors) and all test results have been normal.I suffered from heart palpitations and typical nervous feelings of doom etc. In July I had my 3rd heart sonogram and thought I had finally convinced myself that my feelings were just anxiety, yeah!! BUT on Thanksgiving, I began a whole NEW set of symptoms. Trembling and shaking, muscle cramps and fatigue. These symptoms have proceeded to get worse. I experience trembling and shaking, especially in my neck and head. I have visual disturbances, terrible headaches that make my eyes sore and fatigued. I keep having these momentary spells where my vision gets blurry and I have a strong feeling of passing out, although I have not actually done so. These feelings occur everyday, multiple times a day. At this point my doctor told me that I am trying to hard to find a physiological explaination for the way I am feeling. I was finally getting used to the old feelings I was experiencing. My heart palpitations had stopped in November and then BOOM!! Brand new set of symptoms that are worse than the ones I was experiencing before. Has this happened to anyone before? Are these physical symptoms prone to change? Do they get worse before they get better? My physical symptoms trigger my panic, not places, people or things. Does this seem normal?
