No worries.  
Pence will release his medical records to demonstrate further THAT HE IS NOT RUNNING in 2020.
Trump will counter with his records via Twitter.  The best medical records in the world.  PERIOD.
Mueller will then begin investigating and subpoena Trump's Dr.
Sekulow do the rounds on Sunday talk shows denying Trump ever went to the Dr.
Trump will later say he talked to his Dr. over the phone.
Someone will leak Trumps actual lab reports, and Huckabee Sanders will decry the dastardly leaks.
It's the new normal of American politics.
