hi, I have a cold or something, my nose is blocked, throat sore and a have a chesty cough (green mucus) and last night I had really bad ear ache. When I woke up this morning the sound was distorted in one of my ears, I hear normally in my right ear and then hear an echoed version in my left so that everything, including myself, sounds robotic. It doesn't hurt any more but obviously I'd like to be able to hear... What should I do?
