2. Heart palpitations and chest pain
Some people may feel their heart rate rise and notice a pain in their chest, which is sometimes mistaken for a heart attack. As many sufferers are already in a heightened state of alertness, they may start to worry about these symptoms, which can make them worse, making the person even more nervous and uncomfortable.
Keep in mind, however, that there is a reason for this seemingly inexplicable chest pain. This pain is caused by an excess amount of air in our lungs, which cause them to expand and hit the rib cage, making us feel some pressure and muscle tension. With this tension, our muscles weaken and we feel sharp pains in the chest. If you start to experience this, massage your back, chest, and shoulders to relax the muscles and keep the sensation from worsening.
