I have been getting frequent headaches on my right side and twitching on my left eye back and forth for about 1 month now on and off.. is this ok?

History of headaches: Well, that's a potentially complex situation. Depends. If these are all BRAND NEW SYMPTOMS then, I'd see a neurologist who will likely wish to scan your brain (maybe with contrast) to see if there is anything to explain this. If these are relatively old symptoms with a new twist of twitching of the opposite eye you still may wish to see a neurologist because there may be other things going on.

Need exam: Sounds like stress and or anxiety. Random twitching of an eyelid, which happens in normal people, is called myokymia (an involuntary, spontaneous, quivering of a few muscle cell bundles within a muscle). Myokymia starts and stops spontaneously. In the eyelids, it can last a few minutes to a few days. Often triggered by stress, dry eyes, caffeine, or lack of sleep. Same trigger for migraines.
