I do believe that you would have to file a civil action and use procedures in discovery to get those records. Records from federal, state and local government is covered by FOIA and that can be enforced. Without a civil action you have no foundation to force any citizen to do anything.
If you have a 7 year SOL and you are close to it, then you have been really dilatory and have sabotaged your own case, probably beyond repair.
You can NOT file a medical malpractice action pro se and you certainly can't do it in small claims.
Oh, you could try and it won't get past a summary judgment motion.
