Hello there....
Thanks for the clear pic.
Know Thrissur well and don't see it to have a chilly climate... Perchance are you stationed elsewhere or taken a holiday to some cold ❄️🥶 area in the last 2-3 weeks prior to the onset of this rash?
Could it be possible some medicine was taken prior to the onset of this issue?
Are you a smoker 🚬 by any chance?
All these will point to a condition called Perniosis (Chilblains) or some form of vasculitis or contact dermatitis.
