<h3>Heat Therapy</h3>
<table class="no-break">
  <thead><tr><th width="18%">Rule</th><th>Detail</th></tr></thead>
  <tbody>
    <tr><td><b>When</b></td><td>Morning before exercise, after work, before bed. Use ICE (not heat) for first 48 hrs of a new acute pain flare.</td></tr>

    <tr><td class="td-red"><b>NEVER</b></td><td>Sleep on a heating pad (fire risk and prolonged heat increases inflammation).</td></tr>

<h3>Lumbar Belt Use — Weaning Schedule</h3>
<table class="no-break">
  <thead><tr><th width="18%">Phase</th><th>When to Wear</th></tr></thead>
  <tbody>
    <tr><td><b>Weeks 1–3</b></td><td>All waking hours except lying down and sleeping</td></tr>
    <tr><td><b>Weeks 4–6</b></td><td>During work and any standing longer than 30 minutes</td></tr>
    <tr><td><b>Weeks 7–9</b></td><td>Heavy work tasks only. Do all exercises WITHOUT the belt.</td></tr>
    <tr><td><b>Weeks 10–12</b></td><td>Specific high-load tasks only (lifting &gt;20 kg). Build full independence.</td></tr>
    <tr><td><b>Fitting</b></td><td>Sits at waist level covering L4-S1. Firm but allows normal breathing. Never cinch so tight it restricts breath.</td></tr>
  </tbody>
</table>

<h3>Sleeping Posture</h3>
<table class="no-break">
  <thead><tr><th width="18%">Position</th><th>Instructions</th></tr></thead>
  <tbody>
    <tr><td class="td-green"><b>BEST</b></td><td>Side-lying with a pillow between your knees (slight fetal position). Firm-to-medium mattress. The pillow keeps hips, pelvis, and spine aligned.</td></tr>
    <tr><td><b>2nd best</b></td><td>On your back with a large pillow or folded blanket placed <b>under your knees</b> (elevates knees, reduces L4-L5 disc pressure ~30%).</td></tr>
    <tr><td class="td-red"><b>AVOID</b></td><td>Face-down (prone) — compresses L4-S1 joints and forces neck rotation. The worst position for your spine.</td></tr>
    <tr><td class="td-red"><b>AVOID</b></td><td>Very soft mattresses that cause the spine to sag. A medium-firm mattress is ideal.</td></tr>
  </tbody>
</table>

<h3>Sitting Posture</h3>
<table class="no-break">
  <thead><tr><th width="18%">Rule</th><th>Detail</th></tr></thead>
  <tbody>
    <tr><td><b>Correct</b></td><td>Both feet flat on floor. Hips at 90°. Small lumbar roll (rolled-up towel) behind lower back to maintain natural curve.</td></tr>
    <tr><td><b>Max duration</b></td><td>30–45 minutes before standing and walking briefly. Set a phone timer.</td></tr>
    <tr><td class="td-red"><b>AVOID</b></td><td>Crossing your legs (rotates pelvis, stresses L5-S1). Sitting on the floor. Very low seats.</td></tr>
    <tr><td><b>Screens</b></td><td>Phone and screen at eye level. Do not look down for prolonged periods — forward head posture increases spinal load.</td></tr>
  </tbody>
</table>

<h3>Walking Program</h3>
<div class="box box-blue">
  Walking is one of the most evidence-supported treatments for disc herniation and spinal stenosis. It decompresses the spine, pumps nutrients into discs, and reduces nerve inflammation.<br><br>
  • Walk on <b>flat, firm surfaces</b> (avoid sand, gravel, uneven terrain in early weeks)<br>
  • Wear <b>supportive footwear</b> (running/walking shoes with arch support — no flat sandals)<br>
  • Walk with <b>upright posture</b> — do not lean forward<br>
  • <b>Pain rule:</b> If leg pain increases during walking → stop, sit with spine slightly flexed (lean forward slightly). This opens the spinal canal and relieves stenosis pain.

<div class="box box-red no-break">
  <b>⚠ The #1 Rule for Masons:</b> NEVER lift and twist simultaneously. This is the single most destructive movement for a degenerated lumbar disc. Lift first (with the hip hinge), then turn your feet — not your spine.
</div>

<h3>The Hip Hinge — Your Most Important Skill</h3>
<div class="hinge-grid no-break">
  <div class="hinge-wrong">
    <div class="hinge-title wrong">❌ WRONG WAY (destroys discs)</div>
    Bend at the waist → round the lower back → pick up the load.<br>
    <b>The disc bears 6–8× body weight with this technique.</b><br><br>
    Result: Accelerated disc herniation, nerve compression, and chronic pain.
  </div>
  <div class="hinge-right">
    <div class="hinge-title right">✅ CORRECT WAY (protects discs)</div>
    1. Stand CLOSE to the load, feet shoulder-width apart<br>
    2. Push your hips BACK (not bend knees forward)<br>
    3. Hinge at the hip — keep back FLAT and neutral<br>
    4. Grip the load<br>
    5. Drive through heels, squeeze glutes, push hips FORWARD<br>
    6. Keep load CLOSE to your body at all times<br>

    <tr><td><b>Shoveling</b></td><td>Hold shovel close, use legs not back. Walk material rather than throwing. Alternate which side you throw to.</td></tr>
    <tr><td><b>Sitting during breaks</b></td><td>Proper chair or plank with back support — NOT on the ground. Use a small lumbar roll (rolled towel).</td></tr>

<div class="section-banner page-break">SECTION 10 — When Conservative Treatment Has Failed</div>

<h3>Step 1: Consider Epidural Steroid Injection First (Before Surgery)</h3>
<div class="box box-amber no-break">Consider an injection if ANY of these apply after following this plan strictly:
  <ul style="margin-top:5px;">
    <li>Pain has not reduced significantly after <b>6 weeks</b> of strict compliance</li>
    <li>Sciatica (leg pain/numbness) remains disabling after 6–8 weeks</li>
    <li>Pain is consistently interfering with sleep</li>
    <li>Pain medication requirement is not decreasing despite full compliance</li>
    <li>Pain level is too high to perform physiotherapy exercises</li>
  </ul>
</div>
<div class="box box-blue no-break mt4">
  <b>What injections offer:</b> A transforaminal epidural steroid injection (TFESI) at L4-L5 and/or L5-S1 reduces nerve root inflammation, provides a pain-relief window, and allows more aggressive physiotherapy. Injections treat symptoms — they must be combined with ongoing exercise to be effective long-term. <i>(Bailey &amp; Love's Surgery, 28th Ed)</i>
</div>

<h3>Step 2: Consider Surgery When ALL of These Are Met</h3>
<table class="no-break">
  <thead><tr><th width="30%">Criterion</th><th>Detail</th></tr></thead>
  <tbody>
    <tr><td><b>Conservative treatment has failed</b></td><td>Minimum 12 weeks of genuine compliance: physiotherapy, medications, and at least one injection trial</td></tr>
    <tr><td><b>Progressive neurological deficit</b></td><td>Demonstrable worsening weakness (foot drop, quad weakness) despite treatment</td></tr>
    <tr><td><b>Significant QOL impairment</b></td><td>Unable to work, sleep, or perform basic daily activities</td></tr>
    <tr><td><b>Disabling neurogenic claudication</b></td><td>Unable to walk even 100 metres without severe leg pain</td></tr>
    <tr><td><b>Structural findings correlate</b></td><td>Your AP diameter of ~6 mm already qualifies structurally — final decision based on symptoms + function + failure of conservative care</td></tr>

</table>
<div class="box box-grey no-break mt4">
  <b>Likely procedure if surgery becomes necessary:</b> Lumbar decompression (laminectomy/laminotomy) at L4-L5 and L5-S1, with possible discectomy. A fusion decision requires standing X-rays with flexion/extension views to assess spinal stability.<br><br>
  <b>Your advantage:</b> At age 43 and 73 kg you are a stronger surgical candidate than older or heavier patients — but this same factor also means your body has excellent healing potential for conservative treatment. Surgery is always the last resort.
