Pus, swelling. There will be skin infection around hair follicles varying in size from pimple to large abscess. Typically this is caused by staph or strep. It requires antibiotics and recurrence rate can be decreased by antibacterial soap such as lever 2000, phisohex, phisoderm, hibicleans. S periodic baths with dilute clorox 1 cup per tub will decrease bacteria.
Skin germs. Bacteria are found every where, and some are okay, and some cause disease. There are skin, mouth, intestinal and nose bacteria, that are good for humans, and there are also pathogenic bacteria that can make people sick. Some people, called carriers, carry bad germs on their bodies, which do not make them sick, but can make other people sick. Testing and treatment must be done by a medical doctor.
Perhaps nothing. Difficult to know what you mean by bacterial skin infections, but if these are boils that some people call spider-bites they may be due to methicillin-resistant staph aureus. You do not necessarily have to do anything "wrong" to get these, but occasionally they can be produced by your coming in direct contact with lesions in another person.
Insufficient info. What sort of chronic bacterial infection are we talking about? Some are just inconvenient, others are cause for concern. See a doctor, get a firm diagnosis and appropriate treatment.
Check the Nose. Sometimes people who have chronic skin infections carry the bacteria in their nose. There are ways to treat this that can significantly reduce the occurrence of this problem. See a dermatologist.
Depends on bug and. Location of infection. In general bacterial infections cause pus forming lesions, e.g., boils, cellulitis, skin abscess, infection of burns and other skin disease sites. Other lesions are impetigo, scalded skin, paronychia etc. Special cases include, anthrax, tuberculosis, entry lesions of plague and lyme disease; syphilis, and leprosy.
Is PAIN is the Mandatory Symptom of Bacterial skin Infection? Or also it can be reddish, warm and inflame skin but without pain?
No. Some minor & superficial bacterial skin infections would not trigger any pain. Not all reddish/warm skin is infected. Sometimes such a finding is a minor allergic response to contact allergen or insect bite.
See your Dr. A bacterial infection will need to be evaluated by a physician and usually treated with antibiotics.
See your doctor. You should see your doctor. You may need antibiotics.
Yes. If the area in question is red, firm, hot, and tender to the touch, infection is a possibility, whether pustules are present or not. Staph infections typically have pustules, but not necessarily; and strep (and some other) bacterial infections usually do not display pustules at all.
Culture. Usually the area of infection can be cultured to see what is growing and to help determine what antibiotic is best suited (sensitive) and to which ones the bacteria might be resistant.
Consultation time. Proper treatment will require examination and likely prescription medication. Call your pcp and schedule a visit.
