I'm in a muddle, I don't know what I've got, or if I've got anything. Any help would be much appreciated, I'll try to be as short as possible.
I came back off holiday on April 1st, on the way back, I was quite nervous on the plane, didn't really have a nice time, and in the last days of my holiday I had a badly blocked/runny nose, and on the end of the flight I had a huge pain above my left eye during descent. Possibly due to sinus blockage?
Since this, I've not felt exactly right. It's nearly been a month and it's still not correct. I've still got gradual build up of headaches on the left side of my head. Otherwise, it's just other symptoms like fatigue, and lack of concentration at times. It just seems I'm less 'focused' than I was prior.
What could this be? I'm still not 100%, I can still feel gradual headaches every so often, on the left side mainly.
I thought it could be to do with my sinuses, or maybe even my eyes, I spend a lot of time on the PC due to the nature of my work. With continous strain, I thought this could've caused the headaches/concentration loss.
Any feedback would be brilliant.
