I had this over 15 years. I had a post over a year ago on this chain. Long story short. For past 4 years no more waking up up with ear throbbing. Through a chiropractor issue with my neck. ( Nothing to do with my ear) he had me by a water pillow. Didn't help my neck. But a miracle for my ear. Kept on thinking it's a fluke. Till I stayed in a hotel on vacation. Ear throbbing every night what ever side I was laying on. Went home 1st night no ear pain! Bought a travel size. Never leave home without it. The pain is u have to drain it to get on plane.
