I am due to have surgery on the 24th March to remove some horribly painful endo. However at my pre op today my blood pressure was to high over several readings and I was told that surgery might not be able to go ahead. Bp was about 160/110. They have asked me to go back next week to check again but said lower number needs to be under 100. I will make a gp appointment asap but I am terrified I won't be able to have my op. I've been waiting so long for this, it will improve my life dramatically. Is there anything I can do to reduce my boy in a week?
