I was terrified when I read the title line. I was thinking you must not have strained out the garlic from your garlic oil!
Yeah, not a good idea to stuff the garlic in the ear, not good at all. Just the oil please.
Your story makes sence to me. Your eustachian tube is most likely blocked. You need to get that clear in order for the ears to drain properly.
Horseradish was the herb of the year for 2011. It is a specific for sinus'. Go with the suggestions from Dr Christopher: Grate fresh horseradish-just that alone helps the sinus', then place in a small glass container and cover with the Bragg's (or comparable) apple cider vinegar. Take 1/3 tsp 3x a day for the 1st day, 2/3 of a tsp 3x a day for the 2rd day, then 1 tsp 3x a day for the 3rd day. Each time you take the horseradish, chew it till all the power has gone out. You then have the option of swallowing or tossing out.
Do dry skin brushing of your face, remembering to start at the forehead, then from the eyes down to the top lip, then the mouth down the neck. Afterward, take the sen sei or the deep tissue oil or something of that sort, rub over your sinus' and jump into a hot shower. For further torture, I mean better therapy, you may even do a hot/cold action in the shower. Turning the water as cold as possible for 30 seconds-1 min, then hot for upto 4 min. Repeat several times ending in cold. The hot/cold works as a plunger to the body. For the sinus/ear area, you may even want to have a towel in there to help to direct the hot/cold water to that area.
Now, when talking about putting oil into the ears, it goes like this: 3-5 drops of WARM oil/formula in the ear, rub ear around, pull the ear slightly, move your head a little if you are able to. Plug with a cotton ball. Wait about 1-2 minutes, then turn over and repeat on the other side. You can do Ear and Nerve and the Garlic oil at the same time in each ear. Go to bed after you have both ears plugged. On the 7th day, no oil or formula. Do 50/50 of WARM Bragg's ACV and distilled water to rinse your ear. Turn you head to the side, drop the mixture into the ear, wait a moment, then turn your head to the other side and let it run out. Repeat several times. Then go to the next ear.
