Skin rashes, itching, or swelling from wearing clothes with elastics next to your skin, such as a bra or underwear. Many healthcare products in common usage in a healthcare facility contain latex. If you have a true latex allergy, you should tell the healthcare professionals before you receive care, so that products that don't contain latex can be used for your care. This would be difficult because there is not always a latex free substitution for a product. In some instances, it would also be very expensive.
Most people have no problems, and use latex products all their life.
However, for some people who have developed this allergy, latex-free products are the only solution. The only way to truly prevent latex allergies from occuring is avoiding products that contain latex. You should visit your family doctor, and tell them about your concerns. They can help you decide if your symptoms may be from a latex allergy, or are from some other problem. They will arrange for further testing if it is needed.
