<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have random pain in my lower right side, and sometimes when I m about to pass water I ll get sudden stabs of pain but then it will subside and won t hurt for awhile days or weeks. I ve had protein in my urine before and have had a kidney infection about two years ago. Any suggestions? Should I get it checked out?  <response>: Good Day, and thank you for being with Chat Doctor ! I would advise you to have your kidneys and urinary system checked. Pain during or after urination is always a trigger sign that something might be wrong. I would suggest getting an urinalysis and a kidney bladder ultrasound. This two non-invasive test is very easy to do and would be able to detect about 90 of urinary system abnormalities. Protein in the urine is always bad and tells me that there might be ongoing kidney damage happening right now. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: .comdoctors Chat Doctor. Best wishes.
