Do PFS knee ever go away?

I have Patellar Femoral Syndrome apperantly both my knees are shifting inward... like my right knee is shifting to the left and my left one is shifting to the right. I have this due to overuse...i ran a lot non stop... I've had this for 8 months...the doctor said my condition is moderate which isn't the worst,, I've been to PT and MRI came out OK. (just flounce in meniscus) I just feel so misarable with this pain is surgery the only choice? :(
