Thanks for your question on Healthcare Magic.
I can understand your concern.
No need to worry for heart diseases because your
angiography is normal.
You are having chronic non cardiac
chest pain.
Most common cause for this is
costochondritis.
Another common cause is stress and
anxiety related chest pain.
So better to follow these steps for symptomatic relief.
1. Avoid stress and tension, be relax and calm.
2. Avoid movements causing pain.
3. Avoid bad postures in sleep.
4. Avoid heavyweight lifting and strenuous exercise.
5. Apply warm water pad on affected areas.
6. Take painkiller like
ibuprofen and anti inflammatory drug.
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
