Ocular migraine?: If this is a new symptom, you should see your doctor. Your description suggests migraine, but a physical exam is called for.

Migraine with aura: This is a classical description of migraine with aura. The stiff neck is likely secondary to the migraine. Best to check with your doctor or referral to a neurologist to better diagnose your condition.
