I have small PFO and migraine with aura. Diagnosed by a neurologist. During my contrast bubble echo cardiogram study i developed a Migraine aura with micropsia, dysphasia and sudden sharp pain in the left side of my head, during the valsalva, and went on to have a full Migraine with my normal right sided headache, forty minutes after the aura. Was this sharp pain a TIA, or my migraine? Should I have a CT brain scan. Many thanks. Pat.
A not uncommon problem...
