Hello recently I encountered some problems during my workout routine. As I was doing my deadlifts when suddenly I felt dizziness ,sortness of breath ,increased heart rate a small numbness in my head and my body in general and weakness . I have done all the tests for my heart (triplex,scan,fatigue test) ive checked my theroid and my blood sugar everything ok. I don't smoke and I sleep alot. My doctor sais that it might be psychsomatic . The thing is that everytime I try to lift heavy, this thing happens again.I have adjust my routine but I want to be normal again. I am 30yold 1.80cm 86kg athletic build i don'take supplements or steroids. Thank you.
