Hi, yesterday something bad happened to me. First i started feeling Dizziness , then my heart started beating so fast. I think my blood pressure dropped down. Breathing was pretty hard for a while and it starts to get worst. I started to feel cold and I also started shaking. At some points it got so bad that I thought I need an ambulance. Some times i feel some weird sensations in my head and my left hand start to get numb. I also feel a bit of a twinge in my heart. (PS. my heart reached 128 beats a minute) I took one paracetamol a while ago and a vitamin C couple of hours ago. Now i feel kinda powerless and low on energy and my left ear hearts a bit once a while. I m only 16 and this never happened to me before and i thought this is just from Abdominal gas. My blood pressure got better since last night, i still feel sickness, like something is wrong. I also got abdominal pain and gas along with Diarrhea . I feel some sort of pressure on the bottom side of my nose, i think its my sinusitis . I also have a bit of fever, so im visiting a doctor tommorow. Im really worried this can be some bad disease symptoms...
