From last 2 days and night ,when ever I go to bed to sleep ,in less than 1 minutes feel discomfort like heavy head and I quickly get up from sleep ,also I am feeling tingling and numbness in feet and hands. What all these symptoms are of? What should I do to cure?(Due to study pressure, I am not able to workout since from 4-5 months and gained about 15 kg of weight 50 to 75 kg)
