I Have A Slew Of "minor" Health Problems, And I'm

I have a slew of "minor" health problems, and I'm trying to learn if I have candida overgrowth. Toe fungus (I've been treating for over a year), chronic gum disease (in spite of aggressive treatment under a dentist supervision), foggy brain, random skin pain (flashes of dot-like pain), IBS, depression (taking a low dose of Prozac), irritability, constant phlegm that chokes me at night (I take a decongestant nightly, that helps). Do you recommend I see a doctor regarding candida, and do these conditions seems related to one another?
