I am antibiotics currently for a sinus infection and I have had this pressing pain in my lower back right side. Should I go to the doc to see if it's a kidney infection or will the antibiotics take care of it? The pain comes and goes and it's never really severe. I have no other symptoms of a kidney infection. I cannot lay on my right side because of the pain and sometimes I feel it in the left side, but always in my lower back. Thanks so much for your advice!
Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the pain in lower back to be originating from the kidneys.
There are number of causes for the pain in the lower back and to find out the exact cause, a detailed history is required. The pain might be due to the muscle spasm or herniated disk if it is present on twisting, bending and sometimes even on rest. If the pain is of long duration having started in your teens, a possibility of spondylolisthesis is there where one vertebra slips over the other. Herniated disk can also present with numbness and pain extending to legs. History of prior trauma can also be there in herniated disk. If the back is stiff and sore in the morning then the possibility of ankylosing spondylitis is there in which there is arthritis of sacroiliac joint. With kidney infection i.e. pyelonephritis, it is usual to have fever along with the flank pain. Kidney stones can start a kidney infection and may cause lower back or flank pain, blood and painful urination without a fever.
You must visit your doctor for definitive diagnosis as the same cannot be made online and the treatment can vary according to the cause and may not require antibiotics all the time.
Hope this helps. Take care.
