Plantar Fasciitis Question

I believe I have plantar fasciitis.
I have the typical symptoms: wake up in morning with arch pain, pain after sitting for long periods etc.
95% of the pain is in the arch in both feet.
It isn’t terrible and it hasn’t prevented me from running.
I have used Dr. Scholl’s inserts with some success, although it hasn’t cured it (by any means).
I’ve had symptoms since August 2014.
Is this something I should visit a doctor for or should I attempt more aggressive self-treatment (i.e. motrin, ice, rest, stretching, night splints, etc)?
I can live with it now, but I am worried about it getting worse and possibly ending my amateur running career.
Thanks
