Dear Eswaraji, Though your symptoms are suggestive of just fatigue
, they may be indicative of other conditions too. You need to rule out the following conditions:
1. Is your BP becoming too low... in that case your medication may need t be changed.
2. You need to get your eyes examined with a good ophthalmologist who will also look at your retina
in detail and also check your eye pressure with an instrument called applanation tonometer. At your age, i would expect some amount of cataract
but more importantly we do not want to miss early glaucoma
3. It could be something as simple as fatigue or a change of glasses...
nevertheless, it is advisable that you get a consultation.
