The negative pressures in the middle ear can be due Eustachian tube block ( the tube that connects the ear and the nose ). If you have a habit of sniffing the nose avoid doing that. Valsalva should be done correctly if done inn the reverse manner would not help you. If you have nasal problems like block nose and recurrent colds get it treated.
