I Was Diagnosed With An Aortic Bubble In 2008....now Many

I was diagnosed with an aortic bubble in 2008....now many years later 2018 I'm having a lot of pain..at or under the sternum area..when it was first diagnosed I was prescribed clonazepam o.5mg Q 6..I would only take half of the dose o,25mg..then over the course of a few years it was changed to diazepam..to help relax muscles that don't relax easily !! I didn't have any problem with this until here lately !! I haven't taken any medications for this for years..I'm semi retired from health care after 22 years..I'm 52 years old and I'm scared !!
