Chest & Breathing Problems

In my life, two times I had to inject water as I was not well and too weak. Both the times I faced same problem. I felt excessive cold and I got vomiting. Even my eyes went upwards. Does it happen to everyone. I am worried what will I do if it happens again if I get unwell and require water inject.
