Dizziness and muscle twitching

Hello. My name is Mario from Greece and the last month i am having a problem. Before this month i used to have tired eyes and eye migraines. It was the result of computer usage for work as the doctor said and i should get some eye drops to resolve the problem. Everything was okay for some weeks until i started to get small dizziness and having muscle jerking and twitching. I believed it was still tiredness so i took a break. The point is that after the break i still have jerking and dizziness. I believe it is epilepsy (maybe photosensitive epilepsy) but i am not sure. I never had a seizure in my life even in my childhood that i was too much into the video games. Can you please tell me what to do and what i might have? Thanks for your time and I am looking forward for an answer.
