Pseudomonas is a bacteria that lives in warm, moist areas, such as swimming pools and hot tubs. When it comes in contact with your skin, it may cause a rash known as "hot tub folliculitis." Symptoms of a pseudomonas rash includes raised, red welts, especially in areas of the body normally covered by a swimming costume. If the pseudomonas bacteria get into the ears, it may cause swimmer's ear, or otitis externa. Symptoms include pain, itching and drainage from the ear.
Consult your doctor to verify that it is a pseudomonas infection. Other illnesses and infections can also cause rashes on the body.
Wash the rash, twice a day, with soap and warm water. Dry the area thoroughly with a soft, absorbent towel.
Wipe the area with cotton balls dipped in acetic acid, or vinegar, to help kill the bacteria. Let the vinegar air dry.
Apply an over-the-counter hydrocortisone or topical antihistamine cream to the affected area. The cream will bring down swelling and relieve minor itching.
Contact your physician if the itching worsens, if the rash does not clear up in seven to 14 days, or if you experience a fever or swollen lymph nodes.
Consult your physician for an accurate diagnosis. Your physician may prescribe an oral antibiotic, antibiotic ear drops, or a combination of these.
Take the antibiotic as prescribed by your doctor. Take the full prescription and do not skip a dose.
Take an over-the-counter pain killer, such as ibuprofen, for the pain and swelling associated with the infection. Take the drug as directed.
Consult your physician if your symptoms worsen, or if the condition does not resolve when you have finished taking medication.
A pseudomonas rash usually resolves on its own, without treatment, in seven to 14 days, according to the Skinsight website. A swimmer's ear infection can lead to other complications, including bone infection, according to Medline Plus. If you suspect you have an ear infection, consult your physician immediately.
