Strongyloides will crawl up your throat to be swallowed to complete one of their 5 stages. Strongyloides will give you a itchy throat or allergy type cough especially at nite . Not sure if this is any of your symptoms but anal itching ,rashes in groin and thighs are other symptoms . Alternative diareah and constipation with mucous is another one . Regardless of what you have , ivermectin taken orally and allowing it to be consumed very slowly like candy will penetrate the lining in your throat where the unwanted guests are residing . This will work but several daily doses is what cured my sinus and throat problems and many more doses gave me 98percent of my health back . Hope this gives you some ideas of exterminating the enemy . Wish you well and happy hunting.
