The reason is that tiny, unseen pieces of cat skin are still floating about in the room. Allergic rhinitis is very common. Although there is a widespread belief that young people tend to grow out of allergic rhinitis in their late teens or early twenties, this is not necessarily so. Anyone can have the disorder or can grow into it or out of it at any age. You are particularly susceptible, though, if you are under 40 years of age and have another allergic condition such as asthma or eczema, or if any such condition runs in your family.
Many people suffer from more than one variety of allergic rhinitis, both seasonal and perennial.
Although it can be a lifelong scourge, allergic rhinitis does not normally endanger the sufferer's general health. If you find that allergic rhinitis interferes with your daily routine, see your doctor. You will be asked questions to ascertain how badly you are affected and, depending on your answers, you may be advised against any professional treatment. This is because possible side-effects and the inconvenience of some kinds of treatment may be more troublesome than the condition itself. If you do not know what causes your rhinitis, the doctor may arrange for a skin test that will help to identify the allergens so that you can try to avoid them.
