Thanks for your question on Healthcare Magic. I can understand your concern. Possibility of musculoskeletal pain is more. But since you are hypertensive, we should first rule out heart diseases for your chest pain. So get done blood pressure monitoring, ecg and 2d echo. If all these are normal then no need to worry for heart related diseases. Musculoskeletal pain due to zumba dancing is more likely in your case. So avoid heavyweight lifting and strenuous exercise (like zumba) for few days. Avoid bad postures in sleep. Avoid movements causing pain. Take painkiller and muscle relaxant drugs. Apply warm water pad on affected areas. Don t worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
