If you could stop coughing you could concentrate. Worse it seems everyone is looking around. They're trying to find the source of that nagging sound, but there's no way to control it. Every breath seems to send your throat into a fresh spasm of coughing. It's bad enough to have the itchy watery eyes, running nose and stuffy head, but this persistent coughing has got to stop. Why on top of all the other symptoms do you have to have throat allergies? Changes are good that if you have this nasty little cough you're having an allergic reaction that's impacting your whole body. Throat allergies as well as the running nose and other symptoms are all part of the same package. Your body is sensitive to something in the environment whether it's something you're breathing in or something you've ingested and your body is trying to expel it from your system. That's why your throat is itching and that's why all that nasty mucus is being created.
If your cough is producing mucus as much as you might want to surpassing it isn't a good idea. This is called a productive cough and its clearing the mucus from your lungs and sinus area so that it can be eliminated from the body. Of course this very same mucus is what's making your throat and you so miserable in the first place. To sooth throat allergies you might try home remedies, over-the-counter medicines, or visit a doctor to get a prescription for stronger medication.
A typical home remedy for throat allergies is a soothing tea. Some teas also contain antihistamines which can bring relief from some of the itching and mucus production. Over-the-counter medications containing antihistamines will also manage the itching and mucus production, but be sure to take this medicine with water as it can make your mouth and throat dry. There are also medicated throat drops which can help with the coughing.
Throat allergies should be taken seriously and if the symptoms persist a doctor can prescribe medications. These medications usually also included antihistamine, but will be a bit stronger than those purchased over the counter.
