6. Insect Bites
Mosquitoes, fleas, bedbugs, or mites can all leave itchy red bumps that appear suddenly, usually in clusters.
7. Dermatofibromas
These are firm, small, reddish-brown bumps that feel like hard lumps under the skin—harmless but can persist for years.
8. Folliculitis
Inflammation of hair follicles caused by shaving, friction, or bacteria. Looks like red pimples and can sometimes be itchy or tender.
9. Psoriasis or Eczema
Autoimmune skin conditions that can cause red, scaly, or patchy areas that may start as small dots or bumps.
10. Medication Side Effects
Some meds can trigger skin reactions, including red dots, as a form of drug-induced rash.
11. Viral Infections (e.g., Measles, Rubella)
Some viruses cause red dots or rashes as part of their symptoms. If you also have a fever, fatigue, or sore throat, it could be a sign to see a doctor.
💡 Pro Tip: If red dots appear suddenly, spread, don’t fade when pressed, or come with fever or other symptoms—get them checked out. Better safe than sorry!
