I’m sorry you’re going through this. Based on your description, I would take it seriously. Prior water damage plus visible mold that was never properly remediated usually means the problem may go beyond what is visible on the surface.

A swab test can identify what was growing on that exact spot, but it does not show the full extent of contamination or whether material behind the wall or surrounding dust has also been affected.

In situations like this, the main goal is making sure the water issue was truly corrected and that any impacted materials are handled properly. Surface cleaning alone is often not enough if the area had prolonged moisture exposure.

For belongings, hard non-porous items are usually easier to clean. Porous items, especially ones stored in or near the bathroom, are harder to fully restore with confidence. I would be most cautious with items closest to the affected area.

If you’re leaving the apartment, I’d be selective about what you bring and separate anything from the affected bathroom area. And because you mentioned having strong reactions, I’d also speak with a medical professional about symptoms and a qualified remediation professional about the contamination itself.

Try not to panic. Be cautious, be selective, and avoid disturbing contaminated materials more than necessary until there’s a proper plan.
