Suggest Treatment For Chondromalacia Patella

I have been having symptoms that are close to the symptoms of chondromalacia patella. They have been going on for about a year and have been getting progressively worse. Ibuprofen and motrin do not work. I read somewhere that a stationary bike would help strenghten the muscles. I tried that and I think it made it worse. I am a nursing student and am sitting a lot in class and will be on my feet alot during the clinical setting. I am seeing my doctor in 6 weeks over spring break and was wondering what treatment can be done when OTCs and stationary bikes don't help.
