@sueinmn and @lvon, I know Mayo Clinic has the Dan Abraham Healthy Living Center which has pools and exercise classes but I don't know if any are geared for pain/rehab. It may be worth calling to see - (507) 266-4688

Here are a couple in the area that may offer the services...
-- ActivePT and Sports: https://www.activeptandsports.com/services/specialized/aquatic-therapy/
-- ExercisABILITIES: https://www.exercisabilities.org/rehabilitation/physical-therapy/

There are also pool therapy services around the cities area that uses HydroWorx pools that are geared towards pain relief but I have no experience other than reading their website info - https://www.hydroworx.com/contact/locations/
