Thanks for your question on Healthcare Magic.
I can understand your concern.
Thanks for the detailed history.
In my opinion, you should not worry much about this as
costochondritis is 100% curable.
Only drugs are not useful in costochondritis.
You need to follow some lifestyle modifications for better symptomatic relief.
1. Avoid movements causing pain.
2. Avoid bad postures in sleep.
3. Avoid heavyweight lifting and strenuous exercise.
4. Apply warm water pad on affected areas.
5. Wear rib belt (chest belt) today prevent minimal mobilization of affected areas.
6. Loose weight if you are
obese.
Don't worry, you will be alright and enjoy your normal a well as sex life.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
