Hi I am a 35 year old male. I was practising yoga for a couple of months and doing breathing exercises. Also took some medicine during that period for my allergic bronchial cough. I noticed that the skin on the tips of my fingers and also the balls of the feet were slightly tight with less sensitivity and also with discoloration. Don' t know if this is because of pressure cause while doing exercise or the allergic reaction to the yoga mat. Also was an ayurvedic hair oil during the period and unsure if this had caused by any of these?
