Back issues

Patient: Have had back surgery to fuse L5/S1 with titanium cages implanted with bone grafts. I am in constant pain & have tried therapy several times. Now they have found I have high protein levels in my blood & say they could be linked to other issues but haven’t given me any answers. I’m confused & can’t be treated without any diagnosis. What can I do in your opinion?

Symptoms: Severe back pain radiating down legs
