A few days ago, I experienced an alarming chest pain that lasted just a brief moment. It was on the left side of my chest and felt sort of like a combination of tearing, popping, or grinding. This happened while I was changing my posture, but I'm not sure if that's a coincidence or not. I went online to see what it could be and ended up giving myself a panic attack when I read about something called an Aortic Dissection. At least, I believe it was the panic attack that led to about 3 minutes of lightheadedness, cold chills, and shaking, and not the incident itself, because these symptoms came pretty much immediately after I had read the bit about Aortic Dissection rather than after the pain itself.
The next day, I took work off and went to the hospital walk-in clinic to get checked out. At this point, I had slept very badly during the night due to worrying. However, I had no residual pain. They took my blood pressure (normal), EKG (normal), and the doctor compared my pulse in both wrists (they were the same). The doctor then asked me about some recent things that may have been relevant. I had helped my brother move heavy logs a couple days before, and I am badly out of shape (not overweight, but very weak muscles). I also was trying to push a log into the back of a truck and I hit the end of it against my chest enough to scratch it a bit (but no bruising).
The doctor said a couple things in making her diagnosis. She said that if I had had an aortic dissection, "we would not be here having this conversation". She said that it was a very good sign that the pulse in both wrists were the same. She said that the pain would have lasted much longer than 1/4 second. Also, it is rare to get this at my age (36). She determined that I had most likely strained some tendons or ligaments in my chest helping to move the logs (although I don't know why it would have taken 2 days to suddenly have that kind of pain).
Since coming home from the hospital that day (Tuesday), a few things have changed. I have developed a sensation of bloating in my mid-section, either around my solarplexus or somewhat down and to the left of there. Occasionally there is some mild pain in my left chest that comes and goes. I did have one incident this afternoon that felt like heartburn for about 5 minutes. It feels like my stomach is full most of the time even when it's time to eat (I have not skipped any meals, though). My energy level is still very low compared to before the pain, and my arms feel especially weak. There have been a couple times that I have gotten a cough that felt like it was centered on the same area I had the heart-burn.
I just want to know, is there a point where I should question the original diagnosis and go back?
