Always play in a well lit environment. Take regular breaks, 15 minutes every hour. Discontinue playing if you experience dizziness, nausea, fatigue or have a headache. Some individuals are sensitive to flashing or flickering lights or geometric shapes and patterns, may have an undetected epileptic condition and may experience epileptic seizures when watching television or playing videogames. Consult your doctor before playing videogames if you have an epileptic condition and immediately should you experience any of the following symptoms whilst playing: altered vision, muscle twitching, other involuntary movement, loss of awareness, confusion and/or convulsions.
I had every of these symptoms for a solid year. They didn't found anything. I even passed two MRI scans, nothing.
Of course when the """medical world""" doesn't find shit they blame it on anxiety or depression.
I'm sure it's Lyme but since there's no proper tests to detect it i'm fucked either way.
