So I just recovered from a cold and a sore throat that went on for a week. My throat, which the left side was affected, still hasn't fully recovered. Sometimes my left ear feels blocked. Even when I pop my ears, my left ear will get blocked once again when I swallow my saliva for example. I thought it might have had to do with drinking cold water, but after drinking a glass of hot tea, I had the same thing happen. This doesn't cause any pain or loss of hearing, but it really feels uncomfortable. I still have some phlegm in my throat, so idk if that might have anything to do with it. I really hope someone is at least able to explain why all this is happening, and I really hope it can totally go away.
