Yes!! I was told it was costochondritis! I need to do know what to do about it too! I havent yet to find relief either!

slow stretches, mindful meditation, Dragon numbing gel,
and a warm blanket.
I hope this helps!

Sounds like Costocondritis. Not much you can do. Heat or ice and pain gel. Breath through your stomach. Hang in there 🤗

Yes, the pain can be unbearable. I’ve been dealing with it for years.
