thank-you user for your query. I understand your concern. There are many causes of right sided chest pain and all I can say is that kindly get yourself evaluated thoroughly as there may be battery of causes for it namely Viral Infection, Gastritis, Pleural Inflammation, Gallbladder Diseases, Digestive Tract Disorders, Liver Inflammation and Hepatitis, Injury, Pancreatic Dysfunction, Gastroesophageal Reflux Disease,Thoracic Tumors,Side Effect of Antacid, Overexertion, Stress, Muscle Pulls, Food Blockage etc. On the contrary it may be due to nearing menopause. In your case kindly start taking pregabalin and methylcobalamin combination at night along with that start taking any pancreatic enzymes extract tablet.This will relieve your constipation also. And yes do start isoflavones too as that will reduce your hot flushes. Do consult any gynaecologist to assess your menopausal symptoms and seek a neurologist too. don t worry you will be fine. god bless
