I had seizures after surgery due to severe magnesium deficiency. Surgery worsened my existing (unknown) magnesium deficiency state. I had many symptoms but included lower back pain. Magnesium relaxes the muscles! Magnesium deficiency increases neurotransmitter P. P is for pain!
It would be worth trying magnesium supplements to see how you go. The most absorbable forms are magnesium citrate, glycinate, taurate, or aspartate, although malate, succinate, fumarate are also good. Side effects from too much magnesium includes diarrhea.
Excerpt from Ancient Minerals: "Need More Magnesium? 10 Signs to Watch For"
"3. Do you experience a lot of stress in your life, or have you recently had a major medical procedure such as surgery? Stress can be a cause of magnesium deficiency, and a lack of magnesium tends to magnify the stress reaction, worsening the problem. In studies, adrenaline and cortisol, byproducts of the “fight or flight” reaction associated with stress and anxiety, were associated with decreased magnesium.4
Because stressful conditions require more magnesium use by the body, all such conditions may lead to deficiency, including both psychological and physical forms of stress such as surgery, burns, and chronic disease."

If I were you I would find someone who will listen to you. Then from there get a referral to a neurologist.
