Hi There..I have had an anterior/posterior spinal fusion..l-4, l-5, S1 in May of 2011.  I have had some relief but in September of this year I had the hardware taken out of the right side due to the nerves being really irritated.  It felt better for about a month or two but recently my whole lower back is back to being in chronic pain and I am at my wits end as to what my options are.
Hi, Welcome to Chat Doctor forum.  It appears that there might be some difference in alignment or something else.  I advise you to consult your doctor for diagnosis and treatment. You may need physiotherapy for relief.  I usually prescribe to my patient with such symptoms, neurotrophic injections for 10 consecutive days, ofloxacin, diclofenac sodium, and paracetamol.  Avoid taking potato, other tubers, tomato, egg, chicken, and seafoods till the pain is relieved.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to hasten the recovery.  Wishing for a quick and complete recovery. Thank you.
