4. Chest Tightness
The biggest danger with all of these symptoms of course, is that they make it difficult for you to inhale enough oxygen. You might find yourself having to breathe more rapidly or even starting to panic due to the loss of O2.
One of the responses that you are likely to feel in the body is as though the chest is very tight or compressed. This can occur as a result of excessive attempts to try and breathe, as well as due to the lack of oxygen coming in – the body can end up interpreting this as the lungs being compressed somehow.
The problem is that chest tightness can often cause panic. When you panic, you then breathe even more rapidly, which actually can end up exacerbating the problem and putting you in greater danger. The key then is to try and remain calm and to use your medication if you have some. Note that this symptom can also be a sign of panic attack – or in some rare cases heart attack.
