This is inflammation/infection of eyelid glands.
Welcome to Health Care Magic
Iam Dr. Dadapeer K, an ophthalmologist and I answer health problems related to eye.
It seems from the history that you are having swelling in the right eye lid and forehead associated with headache.
The symptoms most probably indicate inflammation of the eye lid most probably because of infection involving the glands of the eyelids.
The treatment of the condition is by oral antibiotics
, oral anti-inflammatory drugs and antibiotic eye drops or eye ointments
Please do mention answers for few questions as below
Do you have pain of the eye lids?
Do you have redness
of the eyes?
Do you have any pain on eye movements?
Do you have any visual disturbances?
If possible do send me a photo of the affected eye so that I can answer more accurately.
Hope I have answered your question and the information is helpful to you.
