I have a muffled right ear and aching across the chest area. I generally feel under the weather and not myself. Very very tired, slightly sick feeling, lost of interest in everything, no motivation. I have been suffering with my ear on and off since November and each time prescribed antibiotics, but it keeps coming back. I have had a back tooth that has played me up for the last couple of years and I have never had this treated, could this have any involvement in how I am feeling now?
