10 Signs You Could Have Allergies

8. Skin Rash

A skin rash can be caused by a wide range of factors, including exposure to certain plants or even a reaction to a food. Two of the most common skin rashes are eczema and hives, which can easily be brought on by allergens. Once histamine is released, blood plasma begins to leak out of your skin's blood vessels.

If you experience any rash on your skin, it's important to have it examined. If you experience a chronic rash, this could be an indication of something more severe. For those who are prone to rashes, avoid itching problematic areas. This can expose open areas to bacteria, causing minor infections.
