Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, you are mostly having
costochondritis.
No need to worry for major heart or lung related diseases because all your reports are normal.
Costochondritis can cause recurrent
chest pain on different chest areas with
fever.
So follow these steps for better symptomatic relief.
1. Avoid heavyweight lifting and strenuous exercise.
2. Avoid movements causing pain.
3. Avoid bad postures in sleep.
4. Apply warm water pad on affected areas.
5. Take painkiller and anti inflammatory drugs.
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.
