Synovial cyst in 12 yr old boy

My son fell on new years eve and the MRI reports read that his right knee has a bone marrow entusion and his left knee has a complex synovial cyst and small knee effusion. My son has been seen by two orthopedic dr's for a synovial cyst in his left knee, both Dr's want him to be seen by oncology. This has me so concerned. He is not been in school for almost a month or more. He is unable to walk due to his knee giving out and him falling and when he falls on his knee he's in severe pain. He's been in the ER at least 4 times for pain. It just seems that nobody cares at all. We have an appt on March 23 which will be our third opinion, it seems like forever. We've been trying to get him seen by this orthopedics/oncologist since Feb, the dr's office is over loaded and I'm told there is no place else to take him in our area. I call everyday for cancellations. My resources are tapped out and so is my patience per say. One of my questions is,Does anyone know of any resources specifically for juicing or holistic measures that may help my son. At this point any advice would be greatly appreciated! Finances are poor (FYI)Thanks Tweet
