Dear Ma m Thanks for your query to HCmagic A pain which is there at rest and does not come up on exertion, Which lasts for less than a minute, which changes site frequently , which is there the whole day with same intensity, is not likely to be cardiac. Moreover a female who is not smoker, non diabetic with regular menses , not on OCPs and not on steroid therapy is very unlikely to have anginal heart disease. Flickering of blood pressure, when commensurate with level of physical/mental stress is acceptable, unless the variations were extreme. Other possible causes can be a pain from upper gastro-intestinal tract, pain from bone/soft tissue/ nerves or pain from lung or its coverings. Relax, as literature favors you, for a possible non-cardiac cause Feel free to discuss further. sincerely sukhvinder singh
