Can epiretinal membrane cause eye headaches? and can the membrane get worse?? or does it stay the same? ophthalmology

Epiretinal membrane: ERM is like a thin sheet of scar tissue that grows on the retina (back layer of the eye) in some people. No one knows exactly why some people get these and others don't but they can be mild and asymptomatic or severe, causing puckering of the retina with considerable distortion of the vision. ERM does not usually cause headache or discomfort. Surgery is reserved for the more severe forms.
