I know that going to the ER can be a hit or miss with getting the treatment you need. However, since your blood preasure is so high they will have to treat you and trust me they will. I had a similuar experience and I waited four days before going to the ER because in the past I have gone and they would tell me there is nothing they can do. One of the only times I had good treatment at the ER was when I had the high blood preasure. I promise you that they will give you medicine to calm down the high blood preasure. Once you B.P is treated you will finally be able to sleep. Reason being, when you have high B.P. it is nearly imposible to sleep and sleep depreivation only makes everything worse. I hope you take everyones advice and go to the ER because in this case waiting till Monday increases your chances of having additional complications. You are in all our thoughts and I hope you feel better soon.
