Symptoms such as muscle pain in the lower back, nausea and vomiting are sometimes mistakenly associated with kidney blockage, according to HealthGrades.com and MerckManuals.com. Symptoms such as nausea and vomiting are vague and may be indicative of a wide range of conditions, many of which are listed on WebMD.com.
The most common symptoms of kidney blockage are pain in the back or abdomen, nausea, fever, and a sudden increase in blood pressure. These symptoms are often individually associated with other conditions.
Nausea and vomiting alone may be caused by a variety of illnesses and disorders. Some of these conditions are mild and include motion sickness, emotional stress and overeating. More severe causes include gallbladder disease, brain tumors and stomach ulcers, according to Web MD.
Kidney blockages may cause nausea and vomiting in conjunction with severe pain in the lower back, abdomen or side. However, Web MD notes that severe pain itself often causes nausea. Therefore, pain accompanied by nausea and vomiting may not be indicative of a kidney blockage. Severe pain in the lower back and abdomen are also sometimes caused by muscle strain, arthritis or spinal conditions, as noted by Health Grades.
Pain or difficulty during urination may be a symptom of a kidney blockage, however it may also be related to a urinary tract infection. Urinary tract infections are sometimes related to blockages. Patients who experience any of the above symptoms on a recurrent basis should consult a doctor as soon as possible.
