So today I received my test results and it turns out that I do have both an infection and another cyst. I thought it would be one or the other, but I got the two for one deal!
But all the news is not bad. The infection is being treated by an antibiotic and the cyst is small enough that it doesn't necessarily mean surgery. Unless I have more pain I'll be waiting until the end of August before making any decisions. At that time I'll go for an ultrasound to see the size of it- if it's smaller, then we can leave it. If it's bigger, then it'll be coming out.
It's been a crazy ride and from the news today it's not over yet. But at least I know that I'm not riding alone.
