It’s been about 2 months since my piercing and it is still healing. They say 3-6 months but I heal slower because of MS and the meds I take for it. It got infected at the beginning because I touched it, slept on it and who knows what else but I got antibiotics for it and it’s been fine ever since. I’m still using the cleaning spray on it 2-4 times a day because I notice if it gets dry it starts to hurt.
As far as migraines go, I’ve gotten a few since the piercing but not nearly as many as before. I have had headaches every day this week that were strong but not migraine level. In short, I’d do it again because I have no clue if I had migraines caused by foods but I do know they’re no longer as strong or frequent.
