What are the signs of ear infection because this morning i woke up with a ear ache i think its a ear infection but i have a ear tube in that ear ?

Pain/fever/hearing: Tubes can & do become plugged with debris.The involved ear can become infected whether the tube is open or not. If it were open a pus drainage might be found, not so if blocked. You can also have pain with simple blockage if the air has left your middle ear. Yawn a few times & see if it pops open & the pain goes away. If pain persists see your doc.
