Nitric acid

Guernsey, Key Notes to the Materia Medica, 1887, p. 138

This remedy so closely resembles Mercur. in many points, that it is often very difficult to distinguish between the two; Nitr. ae. usually is applicable in dark haired people, and Merewr. in light haired people.

Ulcers; with ichorous pus; having a pricking or sticking sensation, as if a sharp stick or fishbone were present; sensation as if a sharp splinter were being run into the ulcer at the slightest touch,—even of the sheet.

Sensations

As though a sharp splinter were being stuck into the affected part on the slightest contact with anything; same in the throat on swallowing (Hepar, Sulphur); as if a band were around the affected part or parts; as though a band were around the bones; jerking pain in inner parts.

Affections in general, of any kind, appearing in the right eye (e. g., as if a grain of sand was there); right side of the neck; nape of the neck; left hypochondriac region; left chest; inguinal glands; left lower extremity; bones of the head.
