Im 16 and i need help. I have recently have had pain in one and both of my testicles. The pain comes and goes. I has been doing this for about a week now. The pain is mostly in behind my testicle and its almost like an ache. Also, about a few day ago my upper back around my shoulder blades started hurting. It was almost like i crack my back and it would go away if you know what i mean. And on top of that i have had a heaviness in the chest. this just started recently and i have a shortness of breath. Could all three of these be related? If so i relly need to know whats wrong.
