Hi Susan, I have been suffering from POTS for 2.5 years now. Diagnosed in September 2008 and second diagnosis (after the first was questioned) in October 2009. Over this time I have had many weird symptoms. I have experienced adrenaline rush feelings and a wired, hard to settle down feeling, especially at night when laying in bed. I get little tremors and my leg jumps slightly in bed (not all the time but comes and goes). I have had the electric feeling, like sharp electric shocks all over, down my arms and into my hands. Hate it, it comes on quickly and only last seconds but such a scary feeling when it happens. I have sharp pains in my head. (Had three scans over this time, two CT and an MRI), all came back normal. I tried to explain the electric shock feeling and tremors I get to the Dr. He sent me for a nerve conduction study which came back normal. After many ECG's, Stress tests and heart eco, Tilt Test confirmed POTS. It was noted that I had an 'Extraordinarily high output of adrenaline'. I am not surprised that is how I feel. I have also had a few bad weeks. BP really bad. Last week at work 160/98 and stayed up most of the day. Went to GP who first said "I doubt it was that high". Then he took it three times and admitted it was very high. I then spent the next day doing 24hr urine test for pheo(Adrenal tumor)...normal again! I then had three days of low blood pressure 90/60 and even 70/40 at night. So after a week away from work, I dared to go today. I have to get up at 4.40am to arrive at 6am. Felt okay until the afternoon, got very dizzy and bad headache all of a sudden. Got home and had low BP! One of my most troublesome symptoms is chest pain. Also get that hot feeling and have chest pain most days. I started taking beta blocker atenolol 50mg in February 2009 (one in the morning). This seems to help with the palpations in the first half of the day but usually about 90 bpm in the evening. I have taken this for some time now and tolerate it quite well but not sure how much it is doing??? I tried Florinef in March this year, did not agree and have severe headaches for weeks (hence another brain scan). I felt terrible with the headaches and blamed the Florinef so stopped taking it. Not sure now as I still get the headaches, whether the Florinef caused it. Now confused what to take...do not want to have the high BP...I don't know, wish I had an answer for you about the meds! My Cardiologist has told me to take Norvasc but worried that will drop the BP too much? Lastly, my eyesight is suffering, blurry vision and a black eye floater (in my right eye) that has not gone awayI after four months. I am sure there are other symptoms I have failed to mention. I usually handle all of this quite well but have had terrible mood swings and have been so angry lately with the confusion of all this. Trying to stay positive and concentrate on the good things...my family and two beautiful children. I hope this finds you having a better day and answers some of your questions. At the very least, hope you feel less alone and you are not going mad...these crazy symptoms do exist! Take Care, Justine.
