I have a previous history of kidney stones. My lower left back hurts, as in my kidney hurts. Sometimes the I can also feel the other kidney. It isn t really pain like kidney stones, I can just feel my kidneys. Only time I have experienced this is after kidney stones. This is not going away, and the I visited my regular doctor, and they told me I had blood in my urine.
Hello, I got your chief complaint, and it is due to kidney stones most likely you have pain and bleeding in urine. However, to initiate a treatment needs us to know size of stones, location and health of kidneys which would be decided by necessary investigations like ultrasound, urinalysis.  I suggest you visit to emergency room as soon as possible. Remember blood in urine always needs to be taken care immediately. Hope I have answered your query. Let me know if I can assist you further.
