Hello Naveen,
Thanks for your query at doctorspring.com. Firstly, your BP 110/70 doesn't qualify as hypertension. You are a 22 year old male without traditional risk factors. So the probability before performing any test that you have any cardiac disease at all is very low. Cardiac pain is not described as sharp. It is dull aching or burning or heaviness or constriction or choking sensation not necessarily on the left site. It may frequently be precipitated by exercise and relieved by rest. If it happens at rest then it is called acute coronary syndrome and is usually dangerous and associated with sweating vomiting or nausea and feelng of impending doom. On the other hand musculoskeletal pain is precipitated or aggravated by movement and may sometimes hurt by deep pressure and may be relieved by analgesics like those that you have been prescribed. Another pain occuring on one side of chest in a localised area burning sharp and radiatng from front to back is herpes zoster pain which will
be followed few days later by a rash in that location. Probably ypur doctor is correct that you have only a musculoskeletal pain. Your ecg appears normal. It has a early repolarization pattern and a high voltage which may be normal for your age. In view of your atypical symptoms and low pretest probability I would not recommend a treadmill test as it would invariably be negative. But still if you have a doubt lingering in your mind you may go ahead although it would be a waste of time and money. So please relax. Try analgesics prescribed. You may get another ecg done when you are having ongoing chest pain and compare with this one for dynamic changes. But I still feel its non cardiac.
