Every patient has a right to copies of all their medical records.  All you have to do is in writing make a request of each doctor you have seen, and pay a small fee to have them copied.  Be sure to keep copies of all your records including doctor visits and test results.  With these, then you will always be ready for a visit to a new medical practitioner.  Learn and practice asking for medical record copies each and every time you receive a doctor’s diagnosis.
