Hi, Thank you for providing the brief history of you. A thorough neuromuscular assessment is advised with MRI of lumbar spine. As the pain you have which cover the lower back upto the heel, i suspect it to be a neuropathic pain. A thorough neuromuscular assessment is advised. Also, with simple physical therapy training, the symptoms can be controlled by therapeutic ultrasound therapy and TENS therapy. Performing exercises on later stages for strengthening the core, spine, pelvic floor and lower limbs as a whole should give a better outcome. In my clinical practice, most patients respond well to physical therapy. Regards Jay Indravadan Patel
