I have noticed that the skin on the knuckles of my index and middle fingers on both hands has become pale and slightly hard. Could this be caused by the way I squat during meals or while performing Namaz? I am also allergic to sulphur.
The changes in your knuckle skin are unlikely to be caused by squatting. Hard or pale skin on the knuckles can result from friction, pressure, or minor eczema, especially if you are allergic to sulphur. Keep your skin moisturised and avoid potential irritants, and see a doctor if it worsens or spreads.
