Once the symptoms of the ailment have been diagnosed, the real indications and the way they influence the patient accept the most significance for the situation. In sinusitis, the two most imperative elements are odor of the discharge, and the location and quality of the pains. The presence or lack of fever may also give some indication of the nature of the infection, but not always. The origin of the contamination is less critical homeopathically than the trademark symptoms.
Likewise with most homeopathic treatment, there is no one medicine for sinusitis. Instead, the manifestations of the patient matched with the characteristic symptoms of possible homeopathic medicines. The single best match is then given and the results assessed.
