Hello everyone! Can you tell me what I can take from medicine? A cough appeared, it seems like there's a tickle in my throat. There is no temperature, phlegm has been around for a long time, I rinse with Acvuloar. And what can I drink? A cough also appeared, it's hard to swallow, haven't been sick for a long time.
