Hi Sajid,
I'm Lorna, I'm just back from my holiday and catching up. I think I know the eye pressure pain you are experiencing, I get this from time to time too. In fact I did whilst away on holiday, thank goodness I had some of the cream/drops the doctor gave me, My doctor said it was just an eye infection and not too worry. My eyes do not get gritty but do go red and the pressure pain can be sore, It was checked thoroughly the last time I was there and they were satisfied it was nothing serious. Hope you are ok soon. Take care Lorna
