Hey! It's been a while now that I've been having these weird sensation on the right side of my left breast. Sometimes I feel like my heart stops or that it's being pulled out. I always check my pulse when that happens and it seems to be fine. My dad has had a heart attack and so I asked him for help: he measured my pulse, arterial pressure and what else, and he says everything's completely fine except my pulse is a little accelerated (82). He also says that since I'm 16, it might not be about my heart, it might be cramps, stress or just the terrible position I get when I'm on my computer. Also, these past months I've had some really weird eating habits: I never eat the the right time, and even when I'm not hungry, I eat anyways... It's like at lunch and dinner I do not eat, but at any other time I'm always eating. I noticed I'm not fatter but actually lost a pound or 2. I'm not overweight, actually I'm almost underweight, I don't have diabetes or allergies. Supposedly, I'm completely healthy. What could be wrong?
