Hi i was curious about some symptoms i was experiencing and would like some insight as to what might be the cause. So this happened today, it has happened before, many months ago. I get very fatigued when standing or even sitting, i can feel my heart rate rise and i get this almost hyper breathing where i feel like i need to breathe more i can feel it in my chest its like fatigued breathing. It almost always happens when i get up to urinate i feel like i need to hold on to somthing. im a male 17 years of age. I was sort of diagnosed with generalized anxiety disorder after having chest pain strait from morning untill night for 2 months. After hearing that there was nothing wrong with my heart i was sort of reassured and my anxiety has been under controll for about 4 months now. I thought i d mention this incase it might play a role.
