Both sides it equals it out I was told

The piercing jewelry does have to be removed for MRI

I have daith piercing. It has allowed pain to be less intense. I have not thrown up because of the pain since getting it in October 2017. Takes lots of care to heal. Mine just completly healed in May. From my studies it does not matter which ear.

I dont have the piercing so im not sure, i did have a spinal tap and found out i have too much spinal fluid which means pressure on the brain so now on a strong water pill so far my everyday migraines haven't been so intense, have you ever gotten your fluids checked? Just a thought

Have you considered other options that go beyond just a piercing? Like maybe imatrex shots or well there are a million oral meds you could go through and botox pretty much saved my life. I get 8-9 good weeks every 3 months.
