What causes colored spots in vision daily that's worse when i'm anxious. and pulsating vision when coughing?

Couple possibilities: Increased intracranial pressure, either due to pseudotumor cerebri, systemic hypertension, with Valsalva exacerbations. Sounds like you may have scotoma, or - very unlikely - localized occipital cortex kindling. Are you on depakote for seizures or vascular migraine prophylaxis? Are you on HCTZ (hydrochlorothiazide) for high blood pressure or PTC? Consider stopping Ovcon - associated with bad cerebrovascular events.
