<s>[INST] many years ago I was wearing sunglasses and I got a cyst type lump on the back of my head near the two large boney lumps on the back of your head just down from your ears. Now whenever I wear sunglasses, I get a headache. If I take the glasses off, it goes away. I have to wear the glasses as i am outside a lot. What do I do? [/INST] Hi! Good evening. I am Dr Shareef answering your query.At the outset, I would advise you to get your eyes tested by an optician/ophthalmologist and get it treated if positive which would relieve your symptoms. The lump and your headache might not be related , and I would suggest you to get it clinically assessed by a general surgeon. Till then you could go for an anti inflammatory along with a proton pump inhibitor drug for a symptomatic relief.I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts.Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef. </s>
