More medical issues.....

Walking from the garage to work today, I notice a tightness in my chest.... By the time I got to the door, it was to the point I was having a hard time breathing. This is the second time this week that I've had symptoms of an anxiety attack. I have no idea what's going on. Nothing in my life is any different than it was a week ago. It is very annoying! I guess if it continues, I'll have to have a conversation with my doctor......
