Sorry to hear of your concerns. At this time, I'm not familiar with AAA, so I really cannot comment.
Some time ago, my wife and I were in traffic, just pulling out from a light. The traffic in the opposite direction was all but completely stopped (most cars were, a few were pulling up behind) to accommodate a Left Turn arrow for my direction. I watch two vehicles in the opposite side collide, not very violently, but an SUV was cutoff by a small dump truck and struck the dump truck's rear tire, which was still rotating, lifting the SUV onto two wheels, careening across the street, aimed at my car. I was in the curb lane and stabbed the wheel that way, knowing I could not make much more clearance. I don't know how, but he missed, the SUV landing on it's side. Many people rushed to help.
I worry incessantly about my health, but work at a plant that has had several explosions, I've been in car wrecks before, work around high voltage that can incinerate me in seconds if something goes wrong, almost hit as described above. Why do we worry about one facet but ignore others that are much more likely to cause our demise?
For my problem, reading online has me conflicted. Half say don't worry because, and half say worry because, often using the same issues for concern. I'm avoiding reading more. There is no sense. I believe your doctor has confidence in his/her diagnosis, they wouldn't let you walk about if they felt concern was imminent. Just keep on top of it, follow medication suggestions, diet, etc. And above all, something I cannot yet do, relax.
