I have the following symptoms - I have pain in the lower back around the kidneys, i have pain on the flanks pain in the groin and testicles & abdomen. In addition I have tingling in hands & tingling on the top of my headI ocassionally get stinging urination
This could be symptoms of infection or obstruction in the kidneys or the Chat Doctor.  U need to do an ultrasound scan of lower abdomen on an urgent basis and urine tests and visit a nephrologist/ physician soon. Delay might lead to permanent damage to the kidneys.
