Folliculitis is inflammation or infection of the hair follicles.
It commonly appears as small red bumps, sometimes filled with pus, and may resemble acne.
Common causes:
- Shaving
- Tight clothing
- Sweat and friction
- Bacterial or fungal infections
Folliculitis often occurs on the legs, scalp, chest, or buttocks.
6. Eczema or Skin Irritation
Certain skin conditions, including eczema and dermatitis, can produce red patches or small bumps.
These conditions are often linked to dry skin, allergies, or irritation from environmental factors.
Symptoms may include:
- Itching
- Dryness
- Cracking skin
- Flaking
Chronic eczema may come and go over time.
7. Blood Vessel or Circulation Issues
In some cases, red spots may be linked to circulation problems or blood vessel abnormalities.
Conditions affecting blood clotting or circulation can sometimes cause unusual marks under the skin.
Doctors say persistent or unexplained skin changes should be evaluated, especially if they are associated with bruising or fatigue.
When Should You See a Doctor?
While many red dots are harmless, medical attention may be necessary if you notice:
- Rapid spreading
- Fever
- Pain
- Bleeding
- Swelling
- Difficulty breathing
- Unexplained bruising
- Persistent symptoms
Sudden changes in the skin can occasionally signal infections, autoimmune disorders, or blood-related conditions.
