Painful red bumps on your skin might look like acne, but they can signal something more serious. The most common cause is *folliculitis*, an inflamed hair follicle often triggered by bacteria, shaving, or tight clothes. These bumps “may itch, burn, or feel tender,” and can become crusty or form boils if untreated.
Other possible causes include:
* **Ingrown hairs**, especially in shaved areas.
* **Contact dermatitis**, caused by irritation from soaps or fabrics.
* **Shingles**, which causes a blistering, painful rash on one side of the body.
* **Heat rash**, from blocked sweat ducts in humid weather.
To care for bumps: wash gently, avoid picking, use warm compresses, and wear breathable clothes. If shaving causes flare-ups, use a clean razor and shave with the grain.
**See a doctor** if bumps spread, don’t improve in a few days, or come with fever, pus, or severe pain.
Your skin is your body’s warning system. “Don’t dismiss them—listen to your body’s signals” and act early to prevent complications and protect your health.
