Sooo... I'm really not sure if this is whats going on with me or not. But here's what I've been experiencing since March:

I am a very active person. Prior to these symptoms I would wake up early, take care of the animals, make lunches, go to the gym, head to work and walk up to ten miles, then go out with friends or hike after work.
Slowly I began to notice it was getting harder and harder for me to wake up and stay awake in the mornings. I would go take care of the animals and then curl up back on the couch to sleep until I had to get ready for work. I didn’t really think too much about this, I just figured maybe I was coming down with something and my body needed the extra rest. But this happened most mornings in the beginning of March, and if I want to be completely honest, I can back track this to the end of February.
Now, I am realizing that walking, or too much exercise will often trigger some of the symptoms, mainly the chest pain, dizziness/lightheadedness, and the weird feeling in my lungs. The next day I will end up needing to sleep or lay down all day. Even walking my dog can trigger some of the symptoms, and because that’s usually no more than a 30 min walk, I use that to gauge how I may feel the rest of the day. I have been avoiding the gym, and trying to be mindful of my activities overall to minimize the fatigue and these symptoms.
And yes, I am following up with a cardiologist first because this leans more toward heart problems.
The only thing that has been popping up really odd is my bloodwork. The first CBC I had when them symptoms began was a high Hemocrit.
Friday was really bad, and I went back to urgent care, expecting everything to show up normal like usual. But all three of my CBC were high: RBC, hemocrit, and hemoglobin.
