have tried every treatment for my migraines since they began forty years ago. Two years ago my migraines began worsening significantly. I started becoming allergic to all my medications, almost all food, and many more odors than imaginable. My doctors couldn’t figure out why this was happening so they sent me to Mayo Clinic. They immediately tested and discovered I had a B12 level of 7000 and cobalt level of 37. I was told this was the highest they’d ever seen. Unfortunately, my doctor that had added B12 to IVs, IMs, and sublingual supplements never tested my B12 level. I was left with severe allergies and peripheral nerve damage that managed to manifest itself all over my head. Now allergic to all pain killers and migraine medications, Botox,etc., my pain doctor was limited to occasional nerve blocks and daily hyperbaric oxygen therapy, both helped, but were temporary relief. My pain doctor then found a new treatment approved in 2014 by the FDA that is based on stimulating the nerves in your ear to retrain your own endorphines to stop pain, especially head pain. Every 5 days I had a new device with four leads slightly pierced around one ear lobe and attached to a battery pack behind my ear. I used 6 devices and it has been over a month feeling good. I’ve been told people get great relief with 1 to 6 devices. My headache pain went from 7-9 down to 1-3 with this pain lasting up 12 hours 2 or 3 times a week which is hardly even noticeable. My symptoms like light and sound sensitivity are barely noticeable also during those few hours. I’m told for some it’s permanent and others need another round of devices in 6 months to a year. Has anyone else used this device? I called the company directly because it’s so new my doc didn’t have enough information. If you or your doctor are interested the website is http://www.I-H-S.com. My husband and I talked to them directly also for information with great results. I hope this helps my fellow migraine suffers and more people that have used this will speak up with their experience.
