Ive been seeing lights and having sharp headpains for a little over a year now,when I first started seeing them they were little green and purple dots and the head pains were sharp shooting pains that would come randomly throughout the day,then they started coming whenever i put pressure on my head such as coughing, sneezing ,or bending over.Recently I have noticed that whenever i push on parts of my head i feel that same sharp pain,and now the lights are white little dots and im feeling a little nauseous,also my legs have been jerking suddenly,whats wrong with me?????
