Hi. I Have A Non Stop Itchy Sensation Of My

Hi. I have a non stop itchy sensation of my epiglottis. I cannot stop coughing. There is a tickle itch sensation all day long but ti is really bad in the evenings and at bed. I have had this before, several times when with a cold. NOTHING seems to help. I have tried natural essential oils, turmeric tea, honey, lemon, chamomile, lavender......Humidifier and I cnanot handle it any more. it is literally driving me mad... How do I put a stop to this incessant itchiness dry cough and cold. My head and muscles hurt from coughing and NOTHING seems to help
