Hi everyone! I lost my sense of smell, and now I have frequent nasal congestion. How and with what can I treat it? I went to the ENT — the doctor said you don't need to take the test, rinse with sage. That doesn't help. I'm using Rinazol Forte drops. There were no contraindications listed in the leaflet. Do you think that's harmful? And in general, how can this be cured?
