See a doctor if you experience a high fever (100.4°F or 38°C or higher) lasting more than a few days, alongside other symptoms.
Bacterial infections manifest differently depending on the location and type of bacteria. Common signs include:
- Skin infections: Redness, swelling, pain, pus, or warmth around the affected area. Look for streaking red lines extending from the infection site – this indicates the infection is spreading. Respiratory infections: Persistent cough producing thick mucus (possibly green or yellow), shortness of breath, chest pain, and high fever. Consider a bacterial infection if symptoms worsen after a few days of viral symptoms. Urinary tract infections (UTIs): Painful urination (dysuria), frequent urination, cloudy or bloody urine, pelvic or lower back pain. Women are more susceptible. Gastrointestinal infections: Severe diarrhea (watery stools), vomiting, stomach cramps, and fever. Dehydration is a significant concern.
Specific symptoms vary greatly, therefore a proper diagnosis requires medical evaluation. Don’t delay seeking help if you experience:
High fever that doesn’t respond to over-the-counter medications. Severe pain. Difficulty breathing. Signs of dehydration (decreased urination, dry mouth, dizziness). Rapidly spreading skin infection.
Prompt medical attention prevents complications. Your doctor will perform a physical exam, possibly order lab tests (blood cultures, urine tests), and determine the appropriate antibiotics.
Self-treating bacterial infections is dangerous. Antibiotics are powerful medications; their misuse contributes to antibiotic resistance. Always consult a physician for diagnosis and treatment.
