my child was diagnosed with this condition but reading how it affects other people doesn't seem that is what she has

my daughter has chest pain ever since she was 4. We have had all tests done to make sure it was not her heart. She does have heart mummur but not serious condition. Final diagnosis is costochondritis. Reading in this forum how it affects everyone for a long period of time this is not how my daughter feels. She will get a pain whether she is playing or just sitting watching tv or eating. It will last for a few mins and go away. Her next episode won't be for a while like a month or a few days.
