What are the symptoms of skin infections?
Skin infections typically cause redness, warmth, swelling, tenderness, and sometimes pus, blisters, or drainage. Fever, chills, red streaking, or spreading redness are more serious signs that the infection may be reaching deeper tissue or the bloodstream.
The Typical Symptom Picture
Bacterial skin infections such as cellulitis and abscesses share a recognizable pattern. The classic signs are:
- Redness or discoloration of an area of skin, often warm to the touch.
- Swelling, sometimes with tight or shiny-looking skin.
- Warmth — the area feels noticeably hotter than nearby skin.
- Pain and tenderness that is worse than a simple scratch and increases with pressure.
- Pus or drainage — yellow or green fluid, or a painful pus-filled lump (an abscess or boil).
- Blisters or open sores, or a crusting, weeping wound.
What the Symptoms Are Telling You
A flat, spreading area of redness, warmth, and swelling points toward cellulitis, an infection of the skin and the tissue just beneath it. A firm or squishy, painful lump that comes to a head suggests an abscess — a walled-off pocket of pus that often needs to be drained rather than treated with antibiotics alone. Itching, scaling, or a ring-shaped rash are more typical of milder fungal or non-infectious skin problems.
Which Symptoms Are Dangerous
Some symptoms signal that an infection is no longer confined to the skin and needs urgent evaluation:
- Fever or chills — a whole-body sign the infection may be spreading.
- Redness spreading quickly, or red streaks moving from the wound toward the body.
- Severe, rapidly worsening pain, especially pain out of proportion to how the skin looks.
- Skin turning purple or gray, blistering, or a crackling feeling under the skin — red flags for a serious deep infection.
- Confusion, dizziness, or a racing heart — possible signs of sepsis, a life-threatening emergency.
