<s>[INST] I sometimes get a weird pulsing sensation in the front of my brain, just above the right eyebrow area. This just starting occuring within the last year or two.  It is not painful, nor is there any tingling and I dont feel faint or nauseous or anything at all, its just a pulse type of feeling that only lasts a second or two.  It doesnt happen a lot (probably 5-10 times a month max)It actually stopped for several months (maybe 6+) and just recently start happening again every so often.  Whats strange is that Ive noticed it pretty much only happens after Ive been watching TV for awhile or staring at my computer screen doing work.  Any advice or suggestion about what it might be?  Could this be sign of a tumor or something similar? [/INST] Hi, Thank you for posting your query.First, I would like to reassure that your symptoms do not suggest any serious neurological disease and there is no need to worry. These symptoms occur due to eye strain and fatigue, and this explains why you have it after watching TV or looking at a computer screen. Please give some rest to your eyes, and you would be fine. Please get back if you require any additional information. Best wishes, Chat Doctor. Ly/ </s>
