Hello, I have been consistently working out for two years now 5 days a week. All five I do cardio and three days a week I life weights. So far I have been able to run without stopping and without being exhausted or overly tired for three miles. Sometimes however I develop a kind of bad cheat pain on my left side about 1.5 miles in. I have no other symptoms of tiredness and sometimes if I breath extremely deeply the rest of the time it will go away. Is this cause for serious concern? I also do very hard elliptical workouts which always by the end I am more tired than when running but the chest symptom never occurs and I do the elliptical nearly every day.
Hi welcome to Chat Doctor.... You are doing cardiorespiratory exercise regularly .... So chance of coronary artery disease or any heart problem is less.... But still to be on safe side I would like you to suggest following investigation and consult pulmonologist....1. Blood pressure measurement2.ECG 3.Treadmill testing 4. Auscultation along with pulse palpation If needed then echo done ... If no significant cause present then pain could be from musculoskeletal pain.... For that simple analgesic taken....Don't perform all heavy weight lifting exercise once a day for every muscle... Rather you do individual muscle work out daily... Hot pads application useful for pain relief. Sleep posture should be proper.... Hope I have solved your concern... Take care
