CAD symptoms ?

I'm 20 years of age, turning 21 on the 16th of September. I weigh about 340+ lb., and I have hypertension. I was in fairly decent shape before I went into this mass depression phase that started when I was 16. I gained a lot of weight and pretty much stopped taking care of myself all together. Rarely getting outside for air like I used to. For the passed 4-5 years I've been under quite a bit of stress relationship wise. Constant breakups and whatnot I recently picked up smoking and quit just as fast as I started. I used to smoke Black & Milds Wine and Original with the "Cancer Paper" removed about 3 times a week for a little over a month. I could never get addicted to any kind of drug.


I got into online gaming and became a bit of a basement troll, day in and day out sitting in front of the computer for at least 16 to 20 hours a day. Because of it I'd always have anxiety attacks and panic attacks just before I joined game room and started playing. A few years and a few hundred pounds later it seems that I've developed heart problems. As I said before, I have hypertension. And I was diagnosed about 2 years ago, from about 6 years of have never seeing a doctor. I just kind of tossed it aside and didn't worry about it like everything else that was important at the time.

About a month ago I showed slight symptoms of a heart attack/angina. Numbness on the left cheek, and the feeling of blood being drawn from my left arm. Or the feeling of I was laying on my arm and the circulation was being restricted. I went to the ER because I really thought I was having a stroke or heart attack. But the day before that I had the feeling of poor circulation in my right arm instead of my left but no numbness in either of my cheeks. At the ER they ran an E.K.G., blood test, and urine test. The doctor told me everything looked great, my blood pressure was just through the roof. "It was probably white coat syndrome", she says. When I got to the ER it was about 151 over 102. Around the time the tests were done and I had calmed down from all the excitement, it was about 136 over 90.

Before the whole ER thing I was prescribed medicine for my hypertension, Hyzaar. Honestly I didn't start feeling this way up until I started taking it. I was told to keep taking them after I went to the ER, but to make sure that it was the Hyzaar. I stopped taking them for about a week, felt perfect. Then I started taking them about 3 times a week even though I was supposed to take them once a day. Again, testing to see if were the pills. I started feeling a bit groggy during the week, no energy, pretty much like i just got over the flu. Then the next week I took them everyday. That's when the fun started. The numbness in my left cheek and the poor circulation in my left arm returned. But this time it was to the point where the tips of my fingers had gone cold, that didn't happen before. And also I'd have a chest pain that never left, during the whole week. The pains would usually flare up around 4:40 AM or so. I told my girlfriend about it and her and I are worried sick. I told her I was going to set up an appointment with my doctor and spill my guts about every single pain and tingle I'd feel, and I did. He wanted another blood test because the test the ER ran didn't have my cholesterol. During the week of waiting for the results I felt terrible. Chest pains, cold hands, high fever, slight numbness in my left cheek.

When I got the results back he said my cholesterol was "outstandingly perfect", and all my organs were in great shape as well. He ran an E.K.G. as well and it showed no problems what so ever. But he did mention that some of his patients have shown no abnormal heart regularities and still had heart attacks. I don't think I have to explain how much that scared the crap out of me. He took me off of Hyzaar and put me on Genaric Coreg, and 0.4mg of nitroglycerin for the chest pains. After the doctors visit I've only had to use the nitroglycerin tablets twice, once right after the visit and once later on that night when I got a little upset about something. But ever since then I didn't have the on-going chest pains that I had from the following 2 weeks. They jut became recurrent pains. But I started to get scared because now I'm showing a few symptoms of CAD with a few minor differences. I do have the fullness, pressure, heaviness feeling in my chest every now and then. Along with chest pains. I also have the pains along the back, neck, and jaw. The shoulder pain as well. BUT, from what I've read there should be shoulder pain only in the left shoulder. The pains switch from my left shoulder to right. But really it's not even pain. It just feels like I've been doing weight lifting, or picking up a heavy box, the feeling of the muscles being tired. I haven't been feeling dizzy or lightheaded. I have felt a bit of fatigue, but I guess that would happen to anyone that only sleeps 5 to 7 hours a night. And there's also a few weird things I've noticed. Ever since I started feeling this way I've been belching a lot, haven't really had an appetite to eat. And when I go for walks I have absolutely no chest pains what so ever. So from those few little things I try to keep my hopes up and tell my self that it probably isn't CAD, but something more innocent.

This is where my 50 billion questions come in. All of this is really confusing me and I'd really like to know what's going on to be sure if it is or isn't CAD. I've already accepted the fact that it could be CAD, and if I do I'd like to know how bad it is, and how much time I have. But here's what I'd like to ask.

From what you've read, would you say that I do have CAD or my heart could have just gotten weaker from the constant panic attacks and anxiety attacks?

Would long term effects of panic attacks and anxiety attacks show these kind of symptoms over time?

Would it be possible to develop CAD from just having hypertension and being overweight, even though E.K.G. and blood tests show everything is fine?

Is it possible to have symptoms of CAD without actually having CAD?

There were a few other questions, but I can't remember them off the top of my head. These four were the most important questions, though.

I know I've written a lot here for this being my very first post, but I don't know where else to turn. If anyone out there would take the time to read all of it and help me figure all of this out I would greatly appreciate it.
