Have had severe pain in my back x4 days that is worsening. ct shows 3mm bulge at l5-s1 & radiologist noted hydronephrosis in r kidney? what. can i do for the back pain that is natural? movement worsens pain.

If back pain is from the spine then in your age group disc pain is high on the list. If recent trauma or car accident can also consider ligament injury of facet joints.
