Here in the states many practitioners "especially Florida" are complete crap. It has come to the point where typical retail stores like CVS have small clinics in them where they have a Nurse Practitioner that use hilarious diagnosis cards to make their decisions. This can be the case as well for many of the common "URGENT CARE" clinics. Finding a GP is one thing but finding that good GP for you is another. One of the greatest regrets of leaving Illinois was leaving the GP that has known me since I was little and was there from everything from Ear Tubes to referring me to another Doctor I required for whatever reason. Down here for 13 years and I cannot find anyone but an ENT that I can remotely trust...
If he's still in the business, you can always reach out. My mother still contacts my old gp who treated me for over 15 years since I was little and has years of experience and what he doesn't know he knew someone who did. I would try and contact him if possible. Although he might not treat you he could deffinatly try and point you in the right direction
