If you would like to seek help from Mayo Clinic, you can contact one of the appointment offices. The contact information for Minnesota, Arizona and Florida can be found here http://mayocl.in/1mtmR63.

Is Rochester Mayo Clinic a possibility?

If you are in the Twin Cities or nearby, you could check out Childrens Hospital and Services: https://www.childrenshospital.org/centers-and-services#q=slipping%20rib%20syndrome&sort=relevancy&f:_BAC75D8E-5F21-447E-A498-03393BA72D65=%5BPrograms%20%26%20Services%5D

There is a dr at Mayo that does the surgery. I believe her name is dr, kilneker or something like that. Join the slipped rib group on Facebook and feel free to ask me or others on there
