If you have any questions, I have had lots of issues with cervical and lumbar spine plus MRIs, spinal injections, PT, 2 cervical spine decompression/fusion surgeries and 1 lumbar decompression/fusion surgery. I also have lots of experience with neurologists and EMG/nerve conduction studies to test nerve/neuromuscular health and signals to arms/legs. My spine issues have caused many symptoms (pain, weakness, numbness, balance/coordination issues, etc. making standing, sitting, walking, lifting difficult). Surgery has helped some but fusions change body biomechanics.
