Hi and thank you for choosing HCM to post your question. I read carefully your question and understand your concern. It would be better to know about your gender,age,past medical history,smoking status,if you are using other medications ,ect. Bilocor is a beta blocker used for hypertension and hotflashes is a less frequently side effect of it. Just one week of treatment is not enough, so you need to continue treatment and see the results.During this time you need to check frequently blood pressure. If your high blood pressure persists, you need to talk to your doctor and do changes in treatment. Chest pain can occur as a result of cardiovascular,pulmonary,pleural,musculosceletal disease or anxiety states. In the setting of high blood pressure ,you need to exclude cardiac origin of your chest pain. If I was your treating doctord I would suggest to do graded exercise stress testing in conjunction with echocardiography to exclude coronary artery disease and other cardiac causes. A chest x ray is necessary to exclude pulmonary and pleural causes of chest pain. If you suffer from asthma or chronic obstructive pulmonary disease,bilocor can agravate your condition and can cause chest pain.In this case betablocker such as bilocor are contraindicated. I hope my opinion is helpful to you. Wish you good health. Kind Regards Dr .Dushi
