The First Bites

The First Bites
A small eruption
Laura shows David a large, itchy swelling on her arm and wonders whether something has bitten her. The couple cannot find an insect, and David advises her not to scratch while applying calamine lotion.
The practical care also exposes a strain in their relationship. David wants to help Laura leave a job she hates, but she hears his suggestions as criticism and rejects his attempt to guide her.
Symptoms multiply
Over the next few days, more marks appear on Laura’s body, including one near her eye. She scratches until the swelling interferes with her vision, while David urges her to see a doctor.
The symptoms begin as a possible skin problem but quickly become a test of how much either partner can know or trust. Laura is frightened by her body; David is frustrated by his inability to explain it.
The Search for a Cause

The Search for a Cause
A body under scrutiny
Laura devotes the weekend to resisting the itch, bathing, washing bedding, trimming her nails, and searching online for explanations. David searches the apartment for pests but finds nothing.
Her attention narrows around her skin, while David’s searches multiply possible causes without producing a useful answer. Their different strategies make the apartment feel less like a shared home than a site of investigation.
A failed appointment
At a free clinic, Laura is advised to take over-the-counter antihistamines and stop scratching. She leaves believing the clinician has not understood her symptoms.
When she asks why the same household has not affected David, his reassurance cannot resolve the fear. He has felt phantom itches himself, but he does not know whether her conviction reflects a physical illness or mounting distress.
The Specimen in the Bag

The Specimen in the Bag
A discovery that convinces her
Laura digs into a swelling with a cotton swab and shows David a tiny pale speck that seems to move. She identifies it as a parasitic larva and believes it explains why the problem has resisted ordinary treatment.
She stores several samples in a plastic bag and begins a restrictive home remedy. David doubts that the specks are parasites, but he is relieved to see her more hopeful and less consumed by scratching.
An uneasy respite
For a short time, the diagnosis gives Laura a story that organizes her suffering. She can point to something outside herself and describe an enemy that might be removed.
David wants to support her without endorsing an explanation he cannot verify. That distinction becomes increasingly difficult as the symptoms continue and her physical injuries worsen.
The Doctor’s Interpretation

The Doctor’s Interpretation
A crisis at home
David wakes to find that Laura has scratched open a wound beneath her eye, leaving blood across her face. During their argument, they fight over whether medical care belongs on their shared expense spreadsheet and what it means to care for one another.
Their dispute gives way briefly to tenderness: Laura says she needs to hear that David loves her and believes things will be all right. He says the words, then arranges an urgent appointment.
Proof reinterpreted
At the appointment, David describes Laura’s stress and her sleeplessness, unintentionally exposing vulnerabilities she wanted to control. The doctor identifies the bag’s contents as ordinary debris and explains that such collected “proof” can accompany delusional parasitosis.
Laura accepts medication, while David later regrets helping the doctor dismiss her evidence. The diagnosis may explain her conviction, but it does not settle the disturbing possibility that a real bodily cause has been overlooked.
A Living Answer

A Living Answer
Commitment amid uncertainty
David finds a new dermatologist, hoping that Laura’s symptoms will receive a more thorough examination. The appointment disappoints them, but the effort restores a sense that they are facing the problem together.
In the parking lot, David asks Laura to marry him. They marry secretly at the courthouse a week later, imagining that a shared life will give them time to discover how to care for each other.
The evidence emerges
On their wedding night, David feels a swelling pulse beneath Laura’s skin. A creature pushes through her arm, and he pulls a long, living parasite free, apparently confirming that Laura was right to believe something physical was wrong.
The apparent vindication lasts only moments. The parasite turns on David and enters through the soft tissue near his eye, leaving him with a new swelling as Laura sleeps beside him.
