For years I thought I was subject to achy viruses. Everything aches to the bones! Then one day it occurred to me that my husband never caught the "illness" once. We were married 53 years. I get a headache or typical left-side pressure with these episodes. My migraines don't always follow the aura-bad headache pattern, but they are almost always on the left side and my vision blurs or loses acuity.
I get that too. For me it is from my medication Sumatripan. It only happens when I take it.
