Thanks for your question on Healthcare Magic. I can understand your concern. Since you are hypertensive, we should definitely rule out cardiac chest pain at present despite of normal stress test in the past. So get done ecg. If ecg is normal then no need to worry for heart diseases. Possibility of musculoskeletal pain is more likely. So avoid swimming and exercise for few days. Apply warm water pad on affected areas of chest. Take simple painkiller like paracetamol. Don t worry, you will be alright with all these bit first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
