Muffled hearing and diziness feeling.

It started to happen this morning I woke up with kind of dis balance feeling from ears felt like ears are in pressure and hearing is muffled while standing or doing basic work while standing like washing kitchen utensils, I had difficulty in sensing those noise from utensils like they are low. I have No issue while I was sitting watching video on phone I can hear clearly also I can hear noises far away, but kind of feeling edgy since this morning. Also 2 things happened day before yesterday I took shower and put shampoo for washing hairs and I kind of feel that shampoo got into my ears while washing, it didn't effected then and there but it is now. I also have mild anxiety issues so I got anxious and got pressure in back of head which may have agitated nerves there to cause this hearing feeling i don't know what is the cause and why is it happening. Please kindly help I'm a bit hypochondriac.
