Duration of pain
Depending on the cause, the duration of the pain can vary greatly. It is important to consult a doctor if the pain persists for several days or if the pain is very acute and severe. This also applies if the pain often occurs in the morning and disappears again in the course of the day. If it is an inflammation that does not heal completely, it may reappear after a short-term improvement of the symptoms. In this case, too, a doctor should be consulted, especially in the case of abnormalities in the urine, such as blood or heavy foam.
Kidney pain after getting up
If the pain occurs immediately after getting up, it is very important to distinguish it from back pain, which can be caused by tension or restless sleep. In addition, one should also pay attention to whether the pain improves after the first urination. This could be a sign of increased backwater or insufficient drainage of urine, for example due to a stone or an inflammation in the area of the bladder, which is not or only rarely emptied at night. In addition, it can be helpful to try to drink a lot in the morning to bring about an improvement of the pain by “flushing” the kidneys.
Kidney pain is better in the morning
Kidney pain can also behave in opposite ways and decrease in intensity in the morning. This is the case, for example, if the pain is due to a backflow of urine from the bladder along the ureter into the kidneys. This can lead to a dilatation and stretching of the renal pelvis, which causes pain.
The congestion can also be caused by an inflammation along the urinary tract or by a urinary stone. If the stone only partially obstructs the urinary tract, the outflow of the urine formed during the day due to the existing gradient or gravity downwards and movement during daily activities can be sufficient to prevent a congestion. At night, the beneficial influence of gravity and physical activity on the outflow of urine disappears, so that existing urinary calculus can lead to congestion.
This is additionally supported by the low emptying frequency of the urinary bladder. Furthermore, it should be considered that even slightly irritated tissue is increasingly attacked by the concentrated urine at night and can cause pain. If the urinary tract is now emptied in the morning, this particularly aggressive urine flows out.
In addition, fluid is reabsorbed, which dilutes the already formed urine and promotes the formation of thinner urine. An increased urge to urinate in the morning is quite normal. However, with any form of kidney pain, attention should be paid to changes in the urge to urinate, the amount of urine, the frequency of urination and other abnormalities. All these changes may indicate a functional disorder of the kidney or the urinary tract and require clarification by a physician if they persist or are combined with severe pain. A doctor should also be consulted if the urge to urinate is greatly reduced or absent.
