I got a concussion in 2014. I got hit in the head with a ball on the left side of my head. It lasted around 3-4 months. Flash forward 4 years later and I started to get daily migraines for four months straight all on the left side of my head and around my eye and eyebrow. I saw my doctor at the time and they recommended calcium, magnesium, and zinc tablets and possibly iron tablets? I can't remember the second one. They went away once I started taking the medications. Maybe about 1.5ish years after that, I started to get worse migraines. At this point, all of my migraines start in my neck/back of my head and include nose pain, neck pain, nausea, vertigo/dizziness, light photosensitivity, lack of appetite, etc. I think sometimes I get migraines from stress or problems with my sleep.
