Hi dear patient Please relax firstly There is nothing to panic. I need to know your age and occupation actually. Is your occupation concerned with constant reading or constant working on the computer ? If that is the case then your eyes are getting strained. Thats why your developing a condition called a chalezion that is a swelling over your upper eyelid. Now the next question is how will u treat it? You will have to visit an opthalmologist to confirm the diagnosis. If it is a chalezion they will give some medical treatment...if still it does not subside they may have to do a small surgery where they will scoop out the chalezion. Also if you are getting headaches....i suggest u check your eyesight to rule out any vision problem and whether u need spectacles. Hope i could help you out Take care dear
