Hi thanks for asking question. Here first check if you have iron deficiency or vitamin B12 deficiency anemia. Peripheral smear examination done for detection of anemia. If it comes treated accordingly with iron tablet or multivitamin tablet. If you have history of hypertension then hypertension induce heart disease like LVH might be there. Rule it out by ECG or echo. Although you are not smoking, rule out bronchitis or emphysema like obstructive respiratory condition by doing pulmonary function test. If you have celiac disease like malabsorption intestinal condition then it can lead referred chest pain. I hope my suggestion will help you. If no above causes present then chest pain might be by muscular strain or by any unaccustomed activity or improper sleep posture. Take care
