I used to do yoga regularly, but its been 4 months i just cudnt make time to do. i wish to strt it again. during 2 weeks i m suffering from cold, fever, sore throat etc. after taking various types of medicine...i almost recovered from those. but a new problem has started. i am having acidity constantly. whatever i eat my heartburn strts and last for the whole day. i think its because of the medicines i took. now my question is, is there any yoga asan tht can help with my cold and acidity problem?
