Pain caused by the kidneys is typically felt in the flank area, which is in the back, just at the lower edge of the ribs on either side of the spine. Pain caused by the kidneys tends to be sharp, severe and occur in waves.
Kidney infection leads to a sharp, aching pain and even the lightest touch in the flank area is painful.
Fever, nausea, vomiting are additional symptoms.
If you are experiencing dull pain as urinating, you may have some gradual blockage to urine flow.
So, it is important to give information about the character of pain, where is exactly located and if it is spreading.
If this pain becomes worse every day, visit your physician.
