Thank you for sharing something so personal and unsettling. A persistent, foul odor—especially one tied to a specific person or space in your home—can be deeply distressing, both physically and emotionally. While I can’t know the full truth of your situation, I can offer compassionate, practical guidance based on common causes and next steps.
đź©ş First: Consider Medical Causes (Most Likely)
A chronic, sour, or "rotten" body odor that clings to bedding is often biological, not environmental. Possible conditions include:
1. Trimethylaminuria (“Fish Odor Syndrome”)
- A rare genetic disorder where the body can’t break down trimethylamine, leading to a strong rotting fish, garbage, or sewage-like smell in sweat, breath, and urine.
- Often worsens with stress, diet (fish, eggs, legumes), or hormonal changes.
- Not dangerous, but socially devastating. Easily missed by doctors.
2. Uncontrolled Diabetes
- High blood sugar can cause yeast overgrowth (leading to musty odors) or, in severe cases, diabetic ketoacidosis (fruity/acetone breath—but secondary infections can cause foul smells).
3. Chronic Infections
- Sinusitis, tonsil stones, or gum disease can produce a putrid odor that transfers to pillows and sheets.
- Skin infections (like intertrigo in skin folds) can also emit a sour, yeasty smell—especially in hot climates like Phoenix.
4. Liver or Kidney Dysfunction
