Ear Pain can be caused by ear infection or a severe cold. The pain caused by the common cold is sharp or dull or it can be a burning kind of pain ranging from mild to acute pain. The trapped fluid even if it is not infected, exerts a lot of pressure on the ear drum and causes it to swell and throb with pain. Sometimes the trapped fluid gets infected with the same virus as that of the common cold but often a secondary infection takes place. This infection is sudden and very painful in the beginning. The sensory nerve endings inside the eardrum respond with acute pain to the uncommon pressure on the eardrum. After the eardrum stretches a little, the pain eases considerably. Ear pain can also be caused by a buildup of wax. Ear pain can cause fever, irritability, poor sleep, drainage of fluid from the ear, mild hearing loss and loss of appetite.
Ear Pain Home Remedies
Radish
Ear pain can disrupt normal sleep as the pain becomes more persistent when lying down. The trapped fluid keeps shifting and exerts more pressure on the eardrum. Cut a radish into small pieces and soak the pieces in some mustard oil. Heat the oil together with the radish pieces for two minutes. Cool the mixture then strain it and store it into a glass jar. With the help of a dropper put three drops into each ear. Mustard oil and radish have potent antioxidant and anti-inflammatory properties which will not only combat the infection but will also mitigate the pain and swelling.
Peppermint
Take some fresh peppermint leaves and wash them well with water. Crush the leaves and squeeze the mass to extract the juice. With the help of a dropper put a few drops of the peppermint juice inside the aching ear. 
You can also rub peppermint oil outside your ear and all around it. The antimicrobial and anti-inflammatory properties of peppermint oil will kill the infection and will heal the pain quickly.
Garlic
Garlic has tremendous antibiotic, analgesic and anti-inflammatory properties which get rid of the ear infection and the ear pain rapidly and effectively. Crush a few cloves of garlic and extract its juice. Put a few drops of it into each ear. Garlic will instantly relieve the pain by easing the pressure of the fluid on the eardrum. It will also help to dry out the accumulated fluid. 
Ginger
Ginger too has potent antibiotic, anti-inflammatory and antioxidant properties which expel all the harmful free radicals from the body and reduce the inflammation. Grate a piece of ginger and extract its juice. Put the juice directly into your ears with the help of a dropper to get relief from the ear pain. 
Olive Oil
Olive oil has great infection fighting and pain relieving abilities. It not only gets rid of the infection quickly but also lubricates the ear canal and stops the buzzing sensations in the ear. Warm some olive oil and put a few drops of it into the ear canal.
