Same here first time to use so I wasn't sure which post to reply to, anyhow, I started to get pain in my right ear a number of years ago, not sure how long maybe 6 to 8. I got myself in the habit of sleeping on my left but of course would wake now and then on my right.
About 5 months ago I started taking cbd hemp oil for anxiety and about a month into taking it I realised that I no longer had pain in my ear after lying on it. I'm not sure how long it took to work as I avoid lying on my right. People spoke in posts about anti inflammatory working, cbd oil is a very effective anti inflammatory so that might be the reason it worked. The oil I take is from the hemp plant and not the cannabis plant so it can be bought legally in ireland in many shops. I take one that is 8 percent cbd. You put 3 to 5 drops under your tongue hold for 1 min then swallow. Hope this helps, worth a try
