Went to see the consultant last night. I'd made a list of questions and top of that was, "Is doing nothing an option ?" (It was my preferred approach)
Turns out, it is, and it fitted with his advice. He quoted some study to back up "watchful waiting approach" and also said that I could expect these to get bigger over time. Its the getting bigger and being a nuisance/in the way that leads more to surgery rather than pain.
So for now, it back to normal. I'm happy with this outcome.
