2 months ago, I was really tired.I was sitting at my computer at night. All of a sudden my concentration left, and my vision totally opened up. I felt weightless. The Sleepy feeling you get at night left. My thoughts completely stopped. slightly disorientated. when i layed down I had no thoughts, and my heartbeat was very weak, I had to check my pulse to make sure it was beating. 2 days later, still feeling the same way 24/7. All of a sudden my heart took off on me, it had never gone this fast in all my life. Faster than when I go for a run. After 5 minutes it went back to normal. Ever since than my heart doesn't beat 'strong' like it use too. I feel like im going to pass out. My imagination and thoughts are gone. And now I wake up dehydrated every morning. My throat feels swollen, I get tight chest pains, not with a fast heartrate though. Doctor gave me a CRP test and it showed nothin swollen in my body. should i have more tests? Doc thinks it's anxiety. But i feel like im dyin' 24/7 before all this happened. I felt physically and mentally sharp as a tack for a few months prior. I was one of those people that could feel their heartbeat strong without having to check. Now my pulse is so weak. I am a smoker and was an ex-heavy drinker. I did go from 205lbs to 235lbs in 1 year about 2yrs ago. Just before all of this I was just recently back to 205lbs. During my drinking phase I got really bad heartburn. Upper back burn/pain. And really bad chest pains to the point I would have to sit there and hug my chest. That had all gone away after quitting drinking, and I finally felt great again. I also have felt so dehydrated lately, no matter how much water I drink. Test: Blood count is fine, Blood sugar is fine, Kindey/Liver function is fine, No HIV, Blood pressure is 140/93. Does anxiety or panic attacks cause all of this too? My doctor thinks it anxiety and psychosis because I described more of the mental side of it when I saw him. He put me on an ssri and it helped with 'anxiety'. I live in canada and all these tests are free, so I should probably get more of them. I never did get my heart checked out though. They have an ekg at the blood lab down the street and my doctor is one block away from me. I should stop being such a guy and just go request an ekg and a chest x-ray. I'm waiting on my CT scan results to rule out a stroke. I work all weekend. I'll get more tests on tuesday. Forgot to add nausea all the time and loss of appetite! I have had panic attacks before as well, and take an ssri for that stuff. The my heart racing was different than a panic attack. It had to have been going over 180 beats a min, and it was the strongest beat i've ever felt. Felt like it was going to beat out of my chest. I was dizzy, disorientated. And I always get shortness of breath, feels like theres no blood or oxygen gettin to my brain. At work I felt like I wuz going to pass out and needed to sit down. I wasn't panicky though. More afraid for my life. A few times for just one moment my heart rate had returned to normal, like it once was, and all of a sudden my motivation and imagination came back, i felt alive again. Than 5 mins later, I went back to a weak pulse, and back to my strange symptoms.
