Do you prefer to see or ask your primary care physician first, or immediately seek out a specialist?

I see primary care doc twice a year, mostly for blood work.
I have gyn for that stuff. Same one since he delivered my babies.
I feel like we have family plan with ortho.
In my 20s I had an eye disease and had a significant chance of going blind. Still see ophthalmologist at least every couple of years.
Derm for cancer checks each year.
Finally decided to get tested by allergist last year. Won’t need him much in future.
My pcp will tell me I’m the healthiest person she sees the days I go, but still a fair number of specialists, and usually I just go on my own, without seeing primary first.
