Hi, I'm a physician AND I get migraines. It sounds like an ocular migraine, which may or may not be followed by a headache. The one-sided tingling/numbness are
very likely also migraine symptoms, but it's remotely possible they could indicate a more serious blood flow problem that could result in stroke.
I would get checked out by a neurologist or neuro-opthalmologist. Migraine will often repeat itself, so if that's it, it's good to know the diagnosis and have appropriate treatment handy.
On the other hand, some folks get only one ocular migraine in their lives, and you may never have another one--Good luck! (But get checked
.)
