First of all, keep in mind that I am unable to diagnose you because I am unable to examine you, this forum is for educational purposes.
The symptoms you describe are consistent with migraine headaches. It is typical for migraine sufferers to have an aura (often visual- sometimes with squiggly lines or dots, but many variations exist) that can occur before, during or after the headache (Most typically before). These headaches are classically unilateral (on one side) and are throbbing in nature (also called pounding, pulsating, etc). Migraine headaches are typically associated with photo-phobia (lights hurt the eyes), phono-phobia (sounds make the headache worse), nausea and/or vomiting and worsening with movement. It is also common to have confusional spells and the feeling like you are "hung-over" after a migraine headache.
I would recommend that you see a neurologist for several reasons. First, any new or progressive headache disorder (despite the features) should be investigated for possible structural cause (tumor, vascular malformation etc). Second, There are many treatments for migraines that are available now, including Triptans (Imitrex, Zomig, Relpax, Frova, Amerge, Maxalt,etc.) and preventative medications such as Elvail, Topamax, Nadolol, etc.
I hope this has been helpful.
Yes, you should see a doctor. This should not be assumed to be migraines unless and until your doctor is sure they are.
Lots of things cause migraines and visual bluring. Best wishes!
