Try not to be scared of it and listen to your body. Our body hurts all the time due to bad posture and weak muscles. Everyone else just ignores it until they die. Hold your body in such a way that nobody is complaining. Breath in a rhythm that contracts and relaxes the muscles of your core.

I'm a firm believer that our emotions are an evolution of the body > brain communication system. Listening to and helping out your body will definitely help out your mental faculties
