Vision problems

Hi everyone! I recently got sick with the flu and had to take a short break from my lamictal as well as spironolactone cold turkey because I could not tolerate anything. Randomly one day I started having these weird headaches that cause pressure behind my right eye. My vision also keeps going in and out of focus and is a bit blurred as well? It's been ongoing for almost a week now. Has this happened to anyone before? It's been extremely uncomfortable and I'm going to see my doctor on Monday.
