A shocker
I had a TIA not a year ago and they too siad they really didn't know what caused it. They put me through every test in the hospital and nothing pointed to a cause. I did have a high fever a week before my TIA but it is not very reasuring that they never figured out a cause. I didn't and don't have HBP but a little high cholesteral but that has been reduced already. I feel your confusion and worry, but I feel now to live my life the best I can everyday and enjoy my people. Give her a big hug every chance you get.
