On Friday I'm having a scan since it looks like my patella tendons in both knees might be damaged and are not responding to rest or physio. It gets better after about 7 days full rest but I can easily reinjure myself by walking or cycling (things I used to do every day before this happened). This has been going on for about 4 months now.

I've read that the treatment for tears in knee tendons is physiotherapy, immobilisation or *gulp* surgery. Is it possible to heal them without the dreaded cast or surgery? Since it's BOTH my knees I'm getting worried about if I'll be able to continue to do normal daily activities (I'm a student and study in a town 15 mins away on the train) but continuing to walk and stand on them isn't improving matters either. What's the usual course of action if the pain is recurring?
