I am a 15 year old girl who for 1 year has dealt with extreme knee pain on both knees. At first it was thought to be growing pains but due to the extensive time and excruciating pain it was ruled out. I have been to several doctors who don't understand what is wrong with my knees. They hurt all over especially to the lower sides of the knee. They are a bit swollen. They have infiltrated my already with cortizone not having much effect and again recently with a lubricant steroid. Does anyone have any ideas what might be causing me such horrible pain 24/7?
