Have you noticed a red, swollen spot on your hand? Do you think it was caused by a bedbug’s bite? Well, you need to make sure it is indeed from a bedbug, before you try using any medication for it. Bedbug bites usually form reddish lesions on the skin, with either flat welts or swollen bumps.
While bedbug bites itch constantly, they do not usually require special treatment and the reddish spots usually go away within a couple weeks, on their own. Still, as eMedicineHealth suggests, an over the counter anti-allergic medication (in the form of pills or skin creams) should be able to reduce itching and provide comfort to you. In some cases, corticosteroid creams (such as hydrocortisone) can help in reducing the swelling and itching, although these should ideally be used under supervision of a medical professional.
So when you deal with the itching bites the 1st thing and foremost thing you should always do is to put your saliva on it, after few minutes you can wash the affected area with an antiseptic and water.
There are times when a secondary bacterial infection might occur from a bedbug bite. In such cases, you definitely need medical attention. Depending on your condition and the state of the infected spot, the doctor might prescribe an oral antibiotic, or, in milder cases, an antibiotic cream. These medication will clear up the infection and also reduce the swelling.
An allergic reaction to the bite of a bedbug, though rare, can be dangerous, especially if the affected person is young, or particularly sensitive to it.
Do not try to treat such conditions at home. Treating a bedbug bite is not as complicated as you might think. Just focus on your symptoms and do not hesitate to contact a medical professional if you think there might be complications.
