Could this be heart-related?
So, a little about me. I'm a 23 year old competitive bodybuilder and have lifted weights and been healthy my entire life. My diet includes all-natural foods, lots of water, vitamins, and hardly any alcohol. I don't have any history of sicknesses at all, and neither does my family. No family heart problems, either.
What has been bothering me for the past three and a half months is phlegm and every now and then coughing. My nose will run a lot and every now and then when I blow my nose there's blood. More recently, about a month or so ago, I noticed that when I went to the doctor(for my cough) I had elevated blood pressure. It usually is between 125-145. My bottom number is healthy and well below 80. So, there's high blood pressure that I've just been noticing the past month. I've also been noticing strong heart palpitations, especially when I walk around an am active. These have been going on for about a month. I had to stop working out because I would feel too dizzy during the exercises.
So, about a week or so before my sinus problems started(the coughing, phlegm, etc) I tried cocaine for the first time. It didn't affect me at all, actually. I didn't do a ton of it and I walked away and didn't it again for about 2 months. I tried it again about 1.5 months later and same thing, no result. Than I tried it again, for the last time, about a month or so ago. This time I felt it EXTREMELY. I could feel my heart pounding and I began to have problems swallowing. I went to the hospital and they did a heart X-Ray and EKG, and everything checked out fine. They said I was okay. I haven't used it since then nor do I ever plan to, even the thought of the experience makes me sick to my stomach(not literally).
So now, within the past 1.5 weeks I've been having a very hard time breathing during certain times of the day. It will randomly happen.
I've had a Chest X-ray, Chest cat scan, EKG, and blood and urine work multiple times and they all came back negative as to if they think I have heart problems. I'm curious though, what COULD it be? I have always been so healthy. This is really starting to scare me. Someone please help me.
