I too have costocondritis, since I was 7yrs.old. Now I am 51 I used to get it maybe once or twice a year but the episodes were sooo painful I would wind up in the hospital. MOSTLY BECAUSE I*could not breathe and would become hyperventilated. Believe it or not I was not diagnosed until 4 yrs. ago. The down side of this is that the episodes are a little less painful but more frequent and last a little longer.I think it is due to age. Also,when I dont keep up my exercise I find it harder to get back to them because when I try I hurt. So if you do exercise you can never stop!!! It's too hard to get yourself built back up. I used to hate it when I would go to the hosp. or Dr. and they would act like i was a hypochondriac!!! Stress IS a big factor in this disease!!! Hope to hear from you
