I am 64 Male, no hypertension and not diabetic. Since March 2015 I feel pressure (dull pain) on my left forehead and around my left eye. The dull pain sets in especially I work for longer hours with computer and reading news papers. My eye check is perfect. I do not have any pain on my forehead during night and also no pain early morning. The dull pain comes during working hours. While I type this message to you I feel dull pain around my left eye specifically eye brow area. My vision is clear. I also feel the pressure in my forehead while I exert like fretting, clearing bowl and some times while bending towards floor. I had some fluid formation in my nose and a local hospital found it Mucus and not CSF. Please advice me dr. I live in a small village in Ethiopia-Africa as a teacher. Here we have no MRI or CT scan facilities. Any blood tests do you recommend Dr. Regards
