I Slept at old apartment for a couple days with my a old

Oof — that looks really uncomfortable 😟
I can’t diagnose from an image, but I can tell you what this looks consistent with and what to do next.

What I’m seeing

• Lots of small red bumps, fairly evenly spread
• On exposed areas (arms, legs)
• Looks irritated, possibly itchy
• Pattern suggests multiple repeated bites or skin reaction, not a single rash patch

Most likely possibilities (based on the photo + your note about an old apartment)

1. Bed bug bites
   • Very common in old or unused apartments
   • Often appear in clusters or widespread small bumps
   • Can show up after sleeping there for just a night or two
2. Flea bites
   • Especially if pets were ever in the apartment
   • Often affect legs and arms
3. Mite or insect exposure
   • Dust mites, bird mites, or other environmental pests
4. Allergic/contact reaction
   • To old bedding, dust, mold, or chemicals
   • Usually itchier and more inflamed over time

What makes bed bugs especially suspicious

• You slept there
• The distribution (arms + legs)
• The number of spots
• Old apartment = higher risk

What to do right now

At home (short-term relief):

• Wash all clothes, bedding, towels in hot water
• Shower with mild soap (avoid scrubbing hard)
• Use:
  • Oral antihistamine (like cetirizine or loratadine)
  • Hydrocortisone cream for itching (thin layer)
• Don’t scratch — that can cause infection

Very important:

• Do not bring luggage, bedding, or clothes back into your current place without washing
• If itching, swelling, or redness is getting worse → see a doctor

Get medical help urgently if you notice:

• Fever
• Pus, spreading redness, warmth
• Severe swelling
• Trouble breathing (allergic reaction)

If you want, tell me:

• Is it itchy or painful?
• Did new spots appear overnight?
• Any signs of bugs in the apartment (black dots on mattress, blood spots)?

I know this is stressful — we’ll narrow it down step by step 💙
