From the first paragraph of this paper:
In many cases, patients suffer from conditions for which doctors fail to provide evidence – at least of the type that is expected. Owing to the lack of objective ‘signs of disease’ (e.g. x-ray images or laboratory tests), such conditions are often characterized as subjective and they constitute the largest group of complaints in primary care
I've looked at NZ data a few times now and the doctors manage to identify a straightforward problem to code almost all of the consultations to. I doubt that these doctors or the patients are particularly unusual.

From Table 8.4 of this (admittedly old) NZ study which was the first one to come up when I googled.
For example, for non-Maori patients, % of GP visits - by problem grouping for consultations
21.9% Respiratory (Acute respiratory infections,Chronic obstructive airways disease, Pneumonia and influenza, Respiratory symptoms)
17.0% Actions (Preventive procedures, Operations, Therapeutic procedures, Administration)
14.4% Cardiovascular/circulatory (Blood pressure -hypertensive disease; Arteriosclerotic heart disease; Cardiovascular symptoms)
13.0% Nervous system/sense organs (Ear diseases; Disorders of eye; Central nervous system symptoms; Central nervous system disorders)
11.7% Injury/poisoning (Sprains and strains of joints and adjacent muscles; Abrasions; Contusion; Arm fracture; Scalds; Laceration- leg)
10.5% Skin/subcutaneous tissue (Dermatitis/dermatoses; Skin & subcutaneous tissue infections; Symptoms affecting skin/integumentary tissue)
9.7% Musculoskeletal/connective tissue (e.g. Arthropathies ; Rheumatism;osteopathy; chondropathy; acquired musculoskeletal deformity)
8.4% Investigations (History; Examination; Diagnostic procedures/lab tests/radiology)
8.1% Mental (Neurotic, personality and other non- psychotic disorders, Non-organic psychoses)
7.5% Digestive (Gastrointestinal tract symptoms; Oral cavity, salivary glands, jaw diseases; Duodenal diseases;Intestinal and peritoneum diseases)
7.1% Genito-urinary (e.g. Urinary system diseases; Genito-urinary symptoms; Female pelvic inflammatory diseases; Male genital organ diseases)
6.7% Infectious/parasitic (e.g.Viral and chlamydial diseases; Mycoses; Bacterial food poisoning; Viral diseases with exanthema)
etc
If you cast your eye down that list, for most of them there will be signs. And frankly, if doctors in general can't identify signs for most of the things they treat then that would be an appalling indictment of medicine. But it surely is not true. Medicine has got to the point of having all sorts of investigations rather more subtle than 'are bones sticking through the skin?'.
So, how do medical professionals manage to write 'conditions that lack objective 'signs of disease' constitute the largest group of complaints in primary care'? I think the only way that could be true is if all the 'conditions that lack objective 'signs of disease' are lumped together in one group and all the other conditions are split into very small groupss, like, instead of 'Injury/poisoning', there is 'ankle sprains' and 'cuts on leg'...
