Many bug bites are harmless. They itch or sting a little, and the symptoms disappear withing a day or two. There are, however, some types of bugs that cause more severe side effects when they bite human skin. One of these side effects is blisters. Those who are bitten by a bug and find their skin blistering may panic because they do not know what is going on. However, blistering from a bug bite
. is not always a reason to worry.Sometimes the blisters form because they person who is bitten is allergic to the bug that bit them. Some people experience this after mosquito bites. Where most people end up with a small raised area after a mosquito bite, those who are especially allergic may end up with a blister or a large swollen area. If the blisters are larger than the size of a dime, there are more than three of them, or they are accompanied by fever, difficulty breathing, headache or other worrisome symptoms, the person should seek medical attention immediately. Otherwise, antihistamine creams can be used to calm the reaction and the person should be removed from the area where he or she was bitten.Tick bites may also cause blistering on some people. Those who have been bitten by ticks should monitor their symptoms and watch for signs of Lyme Disease and Rocky Mountain Spotted Fever, both of which are spread by ticks.Many types of spiders cause blisters when they bite. The blister generally heals itself within one to two days. If one is bitten by a harmful species of spider, such as a black widow or a brown recluse spider, prompt medical attention must be sought or the consequences may be severe.Bug bites that blister are not always cause for alarm. If the blisters seem overly painful or are accompanied by other symptoms, the best option is always to call the doctor.
