Sounds like Acid Reflux Desiease. My Husband has really bad acid reflux and I use to have it when I was younger. A lot of people think you ony get it just by eating certain foods like tomatos, oranges. anything spicy or anything with a high acidic amount. untrue. if you actually have acid reflux it can flare up anytime. even just by drinking water. and it's not something to fool around with . my grandfather actually passed away from esophagus cancer due to acid reflux disease.
Hi there!
Well, the most common cause of shortness of breath while exercising is either lack of acclimatization or excessive physical exertion. During exercise the oxygen demand of the body increases and one may normally experience some amount of breathlessness. This can be reduced by gradual increase in physical work-load, warm up exercises before a vigorous physical activity and regular work-out sessions. Also the most common cause of chest discomfort during physical exercise at a young age is gastritis/ acid reflux and this can be best avoided by avoiding eating atleast 2 hours before a physical work-out session. If these suggested changes do not seem to help in your case, I would suggest an evaluation by a primary care physician to rule out conditions like exercise induced asthma, cardiac/ pulmonary causes of chest pain etc.
Hope this helps.
Take care!
