Seek medical attn : The treating physician should know about your symptoms as they are in best position to coordinate your care, but otherwise you need immediate medical attention for better symptom control.

Back pain: Back pain can be difficult to deal with. If you are able to go to the bathroom that is a good sign. Inability to not defecate or urinate or foot drop would be indications to be seen immediately. If you have had and injection (I assume a steroid) that can take a day or two to get results. Continue pain meds and perhaps warm shower or bath.
