Two years ago I went to the doctor because I had what I thought was a pulled muscle from lifting a suitcase off the carousel at the airport. (I did by the way) I had a heart murmur since childhood and the doctor decided to check it out. The echo cardiogram showed an issue which led to my first CT scan. It scared the dickens out of me. I found this and other threads and I started to calm down. The unknown always scares me more than facts. So many wonderful people have shared their experiences and information. There are times I overthink and start being concerned more than I should since my measurement is small in comparison to others. I follow my doctor's advice, watch my diet (enjoying an occasional glass of wine with dinner) and have cut my treadmill walk to 15 minutes at 2.0. One of the doctors on the "team" was my husband's surgeon for his second heart surgery so I felt comfortable calling the office. I spoke with a nurse who gave me a wealth of information. I purchased a medical bracelet and have my iPhone set so emergency personnel can see my meds etc. I only travel with family members. Yes, I still get nervous off and on, but I keep going. 146 days until my next cruise. I hope you will find the same comfort i found through these threads.
