Causes for Left Flank Pain

Urinary infections which are also called urinary tract infections are infections caused by bacteria somewhere in this area. All of the parts making up this system may be affected by this infection, but most commonly, you will find an infected urinary tract and bladder. Generally, this infection occurs when there is a bacteria passing through the urinary tract and starts to multiply in the bladder, after which the urine will become infected. When there is no infection, urine is sterile, containing no bacteria whatsoever.


Symptoms of this infection may be mild, unless the condition suddenly gets worse and disease spreads. Urinary infection may also be asymptomatic, showing no symptoms whatsoever. Still, when there is an infection of the urinary tract in question, the symptoms are usually present – common urination, light burning sensation during urination, pain in the bladder, slightly increased body temperature.

One of the most common symptoms of this infection is left flank pain, as the pain may radiate from the bladder into the left side of your body.

If you notice any of these symptoms, you need to visit a doctor as soon as possible. If your doctor suspects an infection of the urinary tract, you may need to provide him with your urine sample so that it can be analyzed for any slime, blood or bacterium. Laboratory analysis of the urine can determine whether you are suffering with an infection or not. Despite this, not a single standard test can determine the difference between an infection of the upper and the lower part of the urinary tract.

Kidney infection or something else?

Many people think of any flank pain being straightly related to kidney conditions. This is in fact a common occurrence, but shouldn’t be taken for granted. Arthritis may also cause spine to ache as well as forced muscle spasms which can radiate into the flank, causing noticeable pain. Many nerves can be found alongside your spine, all of which might get entangled and pressured on, causing specific type of pain in a specific region.

In order to determine which the cause for your flank pain is, tests need to be taken. Urinary tract and kidney inflammations can easily be diagnosed with a simple urine sample. Other causes might require detailed testing and analysis in order to be closely determined – spinal arthritis, muscle spasms, lung emboli, and some types of internal hemorrhage – all valid causes for flank pain.

In order to determine the exact cause of your flank pain, it’s necessary to visit your doctor and describe all of the symptoms you’re dealing with closely. Every single bit of information can help your doctor diagnose the appropriate condition which will be treated soon after with proper and effective methods, whether these are medication, physical therapies or anything else. Do not delay this visit as you need to find out what the pain all about is and how you can get over it in the quickest and most efficient manner.
