This pain is multifactorial along with valvular regurgitation, stress induced acid reflux, decreased immunity levels of the lungs, other muscular or skeletal related issues, referred pain from certain nerve endings. Medicines are not going to help much in such case, Lifestyle modifications will work better - Chat Doctor. - Regular walking, exercises, YOGA.- Avoidance of stress, anxiety.- No smoking, alcohol.- Regular sound sleep of 8 hrs.
