I'm having some trouble after using Kala hit spray on my balcony; I might've used too much. Ever since then, I've been having breathing problems and discomfort. I saw a cardiologist who ran several tests, like hemoglobin, thyroid, chest x-ray, and echo, but they all came back fine. Even with that, I'm still feeling uneasy and it's hard to breathe. What should I do?

Normal,nothing to worry ok.
