Aye, I went to the Doctor last year about a Knee Niggle to see about getting an X-Ray and I did. Nothing showed up so I just left it at that and never went back because I never had any major issues. Where as Osgood Schlatter was when I was young. I'm 23 now. I'll be okay, I'm not dying but I am hoping to get in to the Army. I'll give myself a couple of months, I'm good with that. Good luck Cakey.
I fact that you are needing radiographs suggests that you are still having symptoms.
It is probably worse that you did not return as there will not be a note on your records of how long you have been symptom free (especially since you were under investigation last year)
