ear pressure problems???

Approx 8 months ago my mother developed a problem with her ears, she describes them as feeling full of air, blocked, sometimes painful and a slight loss of hearing. She had a scan and hearing test which revealed nothing, at some point both eardrums were retracted but her doctor has since said both are fine.She has suffered with tinitus for a number of yrs but says this is a different feeling altogether. This problem has caused her to suffer from severe anxiety and depression meaning that she barely able to leave the house and sits in her bedroom most of the time not leaving her with much quality of life. Her feeling is that it is to do with the pressure in her ears but no one in the health profession seems to want to listen or help. She is deperate.
