I have frequent headaches, occasional ocular migraines, and heartbeat skipping episodes confirmed by EKG.  Brain MRI indicates multiple areas of focal white matter change in both hemispheres.  I have a high-ish platelet count and slightly high BP
There isn't really enough for a clear answer. Migraines, even ocular migraines are not uncommon. The same is said for palpitation. The MRI findings have to be correlated with the reason the test was done. Sometimes they are present with no clear explanation. You are correct in the report of you blood pressure, slightly high. It warrants attention. The simple diet and exercise recommendations are difficult but may be the most rewarding. Your primary doctor is the best judge of the need for testing as opposed to the chicken soup recommendations.
