I had a catheterization procedure on Wednesday. I had no blockages. My blood pressure went up to 160 during the procedure and they had to give me something to lower it. I spent Thursday and most of Friday resting, but had a big coughing fit yesterday afternoon. Today I was feeling faint and have seen that my blood pressure is going up and down. 79/51, 82/58, 90/63, 81/61, 97/61, 70/57, 107/72, 105/71, 110/76, 84/66, 98/66, 94/62. Any ideas of what is happening?
