If it really was "minor" I'd probably just use Google or check out some websites like the Mayo Clinic or WebMD to look up my symptoms and read suggestions for addressing the issue. YouTube can sometimes be of help as well. On the other hand if it was something major or an ongoing thing I'd make an appointment with my doctor.
I would go to my doctor. Here she works together with the pharmacist. I have diabetes and doctors see so many people it amazing they remember you as well as they do. She just calls the pharmacies and they work out a plan together. It keeps me from getting meds rpthat shouldn't be taken together.
I would go to a doctor. No one who is not medical professional can decide whether a health problem is minor or major in most instances. In addition, a pharmacist is not the right front-line health professional to deal with patient's complaints.
