Thanks for using this forum. From the description of your symptoms, it points out towards some ear infection
which can either involve the inner or middle ear canal
due to bacterial or fungal growth. Avoid swimming or making the ear to come in contact with water. Avoid scratching and using any ear buds too. Have a prompt checkup with your GP before trying any home remedies
. Usually an antibiotic course is required to curb this infection within the ear canal. Hope this helps. Regards.
