Pressure on the kidney or ureter from a tumor outside the kidney can cause extreme flank pain. [7] Local recurrence of cancer after the removal of a kidney can cause pain in the lumbar back, or L1 or L2 spinal nerve pain in the groin or upper thigh, accompanied by weakness and numbness of the iliopsoas muscle, exacerbated by activity.

Paroxysmal nocturnal dyspnea or paroxysmal nocturnal dyspnoea (PND) is an attack of severe shortness of breath and coughing that generally occurs at night. [1] It usually awakens the person from sleep, and may be quite frightening. [2]
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
When meteorologists use the term: low pressure area, what are they referring to?There are quite a number of scientific terms commonly used in weather forecasting and low pressure is one of the ...
Furthermore, the patient may still experience the effects of their alpha-adrenoceptor antagonist, which causes lower blood pressure. [126] First-line treatment for postoperative hypotension is aggressive fluid resuscitation, which is why ensuring the patient is well-hydrated (see above) prior to surgery is so imperative. [125]
To be diagnosed as proctalgia fugax, the pain must arise de novo (meaning the absence of clear cause). As such, pain associated with constipation (either chronic, or acute), penetrative anal intercourse, trauma (such as tears or fissures of the rectal sphincter or anal canal), side-effects of some medications (particularly opiates ), or rectal ...
Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and anxiety. [3] A low partial pressure of carbon dioxide in the blood also causes alkalosis (because CO 2 is acidic in solution), leading to lowered plasma calcium ions ...
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), [ 1 ] while high-pressure areas are associated with lighter winds and clear skies.
