Hello. I am recently recovered from a cold, which seems to be cleared up, but am left feeling very mucus-y in my sinuses, and this is causing me to cough, a lot. It probably sounds odd, but it feels like I have the urge to cough something out from inside my head, which at the same time seems impossible! I do not have any residual sore throat from the cold, just this mucus cough. Is there anything I can do myself to drain my sinuses?
