Frequent/occasional severe abdominal pain
| Severe acute or prolonged abdominal pain is a possible symptom of many serious conditions. You are advised to seek medical attention as soon as possible, unless you already know the cause of the pain. |
(Slightly/very) black/tarry stools
| Blood, as seen in the stool, can originate anywhere along the intestinal tract. A black stool (called melena) usually means that the blood is coming from the upper part of the tract. At least 4 Tablespoons (60ml) of blood must have been lost in order to make the stool black. Maroon-colored stools suggest that the blood is coming from the middle portion of the intestinal tract, and bright red from the large bowel or rectum. If stools change color suddenly, it can be evidence of internal bleeding which requires immediate medical attention. The ingestion of black licorice, Pepto-Bismol, or blueberries can all cause black stools or false melena. Stools should be tested for the presence of hidden blood. |
Frequent/significant red blood in stools
| Significant bleeding from anywhere in the body requires immediate medical attention. Small amounts of red blood, especially on the toilet tissue, are most likely from hemorrhoids. |
Pain in one eye or pain in both eyes
| Severe eye pain should be investigated aggressively to prevent the possible consequence of blindness. |
Chest pain when breathing
| The sensation of a "catch" at the end of a deep breath is clinically important as a symptom of pulmonary embolism (a clot to the lung). This requires immediate evaluation by a physician. |
Significant/severe neck pain
| Severe neck pain can indicate a potentially life-threatening condition, such as meningitis, encephalitis or a subarachnoid hemorrage. |
(Severe) stiff neck
| A very stiff neck can indicate a potentially life-threatening condition, such as meningitis, encephalitis or a subarachnoid hemorrage. |
