Food Allergy rash come in a host of sizes and shapes. It can be hard to determine what it is that is causing the rash. In many cases the rash is localized to one specific area which makes determining what is causing the rash a bit easier. Most people are wrongly under the impression that a skin rash means that you have touched or come into contact with something that you are allergic too.
In some cases the rash is caused by something coming from inside your body not something that you have touched. The pattern of the food allergy rash can help you to understand the cause a little better. For example if you break out in a rash around the collar of your shirt or at the cuffs of your sleeves or even at the waistband of your under garments than the rash is likely being caused by something in the material of the clothes you are wearing or the laundry detergent you are using.
Types of Rashes
The type of food allergy rash can range from angry looking red patches with little white pus pockets to something that is small and barely noticeable. In some stages of the rash you may experience some serious discomfort that will range to a feeling or extreme itchiness to throbbing and burning. The type of rash is not really an indicator of the cause.
The type of rash that you will break out with whether it is a food allergy rash or a contact rash will entirely be dependent on
how allergic you are and how sensitive your skin is. Rashes are caused by an immuno reaction to the allergen. Histamine is released into the body to fight off the invader (whatever it is you are allergic to). That histamine causes the reaction in your skin. It also causes your eyes to water and your nose to run.
One way to tell the difference between a contact allergy and a food allergy rash is by looking at your skin and looking for a pattern. If you can see a clear pattern like where your arm was resting on a desk or where you applied makeup than you are likely experiencing a contact rash.
If you can not see a clear pattern and you are just breaking out randomly it can still be a contact rash but if you have tried new foods it is very likely a reaction to a new food. Another tell tale sign of a food allergy rash that may manifest as a rash is that you may notice a rash around your mouth!
Food allergies can be deadly literally. There are many people that randomly develop a shellfish allergy after years and years of eating shellfish and because they do not realize they have developed this allergy. They notice minor symptoms but ignore them and wind up hospitalized with a severed reaction after consuming large quantities of the food that they have developed the allergy to.
If you have developed a sudden rash after eating even a familiar food and you experience swelling of the face or neck you should immediately seek medical treatment. Taking an antihistamine as soon as you notice the rash has developed can help to keep any other more severe complications from developing.
You can determine if you are developing a food allergy rash by isolating certain foods from your diet that you have consumed prior to breaking out with the rash. Keeping a food diary will also help you to recognize which foods you need to isolate.
