Dear Readers,

I.S. writes Lifeline from a Constant Spring P.O. address. I.S. is worried about a skin problem. In her letter, she makes reference to an article by Lifeline earlier this year. I.S. believes she has the same problem. She has been bitten on her feet by insects, which is a recurring problem. This results in spots which spread, itch, and eventually become quite large. The rashes have most recently occurred on her upper limbs and on her elbows.

It can be difficult to write about skin rashes without seeing them; however, Lifeline will make the effort.

Bites from common insects such as mosquitos, fleas, and ants can cause itchy welts on arms and legs. Usually, bites are no more than an annoyance causing slight local swelling and mild irritation.

Bee and wasp stings can cause swelling and stinging at the site. Occasionally, people have allergic reactions to insect bites which not only cause more generalised swelling and itching, but can also cause difficulty breathing as well as wheezing.

For most insect bites, the application of ice or a cool compress to the area reduces the spread of histamines, which cause the itching and swelling. The application of a cream containing a steroid, analgesic, or antihistamine will also helps to contain discomfort. Individuals who are more sensitive to insect bites will need to take oral antihistamines to contain the swelling and itching.

Occasionally, oral steroids are also necessary to control a bad allergic reaction.

Another complication is that the itching of the bite can result in the area becoming infected with bacteria.

Several bacteria can infect the skin. Some, like impetigo, can even be contagious. Impetigo is a superficial inflammatory disorder where small vesicles form on the infected area, rupture, and form crusts.

The lesions can heal leaving behind dark, post-inflammatory spots, which can be unattractive. Untreated, the skin infection will often still clear up by itself in a month or so but does tend to leave, on some skins, darkly discoloured spots.

Usually, if mild, this skin infection is best treated with an antibiotic cream or ointment. Oral antibiotics are best used with a more extensive rash. Often, in individuals with known skin reactions to insect bites, the application of a cream or ointment, which contains both antibiotic and a steroid, at the time when first bitten, will help to prevent both the itching and possible subsequent bacterial skin infection.

As prevention is always best, susceptible individuals should try not to get bitten by wearing pants and long-sleeved shirts when necessary.
