My first bout of Covid was January of 2021 and have had a continuous chronic cough since then. I've tried different inhalers etc. but nothing works and they actually seem to increase the phlegm in my lungs after 4-5 days of use. Just had my latest round of Covid this last month (started on July 3) and this has been by far the worst one - I've had it about five or six times. I have not been tested as that seems to have fallen by the wayside here in Canada but the symptoms (loss of taste and smell, sore throat, horrendous cough, infection of eye, nose, ears, throat and lungs) are always the same. I'm slowly improving but since 2021 nightly coughing has been a problem. Sometimes there is phlegm but generally just a dry hacking cough that won't quit. It has affected my social life as well because the coughing will start out of the blue and not quit. Drinking water, taking cough drops or cough syrup have limited effects, and I think the system eventually becomes so used to them that they have almost no effect. I do have long Covid and the cough is the gift that keeps on giving. I sympathize with you and would love to hear if anyone has found a solution. Good luck.
