Thanks for your question on Health Care Magic. I can understand your concern. Since you are having heart disease from birth, we should first rule out cardiac chest pain in your case. So immediately consult doctor and get done 1. Ecg 2. 2d echo 3. Stress test. If there is some problem in any of the above mentioned tests then you need to consult cardiologist and start appropriate treatment. If all these reports are normal then no need to worry much for heart diseases. Musculoskeletal pain is more likely. So tale painkiller and muscle relaxant drugs. Avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. Apply warm water pad on affected areas. Don t worry, you will be alright. But better to rule out worsening of heart disease first. Hope I have solved your query. Wish you good health. Thanks.
