Hi. Thanks for your query. There may not be a relation between the pulled muscle and High Blood Pressure directly. Your anxiety / pain / fear can temporarily increase blood pressure. You are advised to take Blood Pressure on three different days , it may settle by this time. If the BP does not come down , get an opinion of a cardiologist and a treatment for the same. The pain in the abdomen may be really due to pulled muscles as you rightly suspected. A painkiller and a muscle relaxant along with strict best should help you completely recover unless there are associated problems like pleural infection and inflammatory process going on in the upper abdomen or a lower chest. Yet is is always better to confirm or rule out -
