Hi everyone. For the backstory, I had Migraines with Aura frequently from the ages of 10-17 and then they just stopped. I am now 29, and 16 days ago I began experiencing what I can only compare to as a migraine aura. It is in my right field of vision only and while it isn't there 100% of the time it is very persistent. Sometimes its flashing lights, sometimes the kaleidoscope but always in the exact same spot. Of course at first I flashed back to my teens and thought I was just having a regular migraine again, but the headache, vomiting and paralysis never came. I have been experiencing intermittent tingling/numbness in my back, arms and legs, but this started a few weeks before my aura. After day 5 of the aura I went to the ER and had a clear CT scan and the diagnosis was "Headache" even after I told them repeatedly I was in zero pain. I did some googling which led me to "Silent Migraines". I followed up with my PCP the next day and he had never heard of silent migraines when I told him what I found, but immediately said yeah he thinks that fits after he looked it up himself. He sent me to ophthalmology to be safe and my eyes are 20/20 totally fine and the eye Dr. also jumped on the Silent Migraine train but said that if I still have body tingling I should get an MRI (as I was sitting there with tingling).
So heres my question/concern. I am totally happy accepting a diagnosis of "Acephalgic Migraine" but im concerned with the duration of the aura. 16 days? My auras previously never lasted longer than 20-30 minutes max. Could I really be having a silent migraine for that long? or could I be having multiple silent migranes daily? Something in me is just really feeling like there is more, or I should be questioning this further, but maybe someone else here has experienced something similar?
