The feet are very susceptible to insect bites. Often in the summer we wear open shoes or sandals. Insect bites are a form of injury that results in puncture wounds or lacerations made by insects. Insects often inject formic acid, which can trigger a reaction, including redness, swelling, pain or itching. There is always a risk of an allergic reaction which can potentially be life threatening.
The first line of defense against insect bites is not leaving skin exposed. Socks and closed shoes go a long way in creating a barrier to the insect. Utilizing insect repellient is also very effective. Some sunblocks also come with insect repellient.
Most insect bites result in a small, itchy bump forming. They can be treated at home and usually are gone within a few days. I suggest applying ice to the area of the insect bite to counter inflammation. Steroid creams are also effective and relieve itching. A person who has an allergic reaction or severe reaction may need to see a doctor for more powerful medications to counter the reaction. Do not hesitate to see a doctor if in doubt. This is definitely a case of better safe than sorry.
