I can't walk!!!

Well I can still walk.. but it hurts. A lot. 

Shin splints. Tendinidous. What ever name you want to put on it. It feels like knives are in your shins and calves, and whenever you take a step someone twists those knives. I've had this pain since last indoor season but it never was this bad. It hurts when I start doing anyhting physical, specifically marching up on the balls of my feet during indoor. The extra weight of a drum might help make them worse too. But they feel like a constant muscle burn.. times 30. When I finish marching the show I collapse because my legs hurt too much to put any weight on them anymore. 

I got really frustrated today though. About a week or two ago I went to the doctors for the second time for this problem(the first time he just gave me asprin and told me to sit in a wheelchair for 3 months if I wanted them to go away) and finally thought I was getting somewhere. He gave me a referal to a physical therapist and told me they would probably do ultra sound therapy and it would heal them reletivly fast. Well today was the physical therapist apointment and it did not go well. The paper said I had tibia tendenidous(tibia meaning leg). I sat down and the physical therapist asked me if i did anyhting to hurt me knee. I told her it was my shins not my knee and she said "OHHHH that's what tibia means". She takes measurements gives me a little rubber band and shows me some exercises that make it feel like I was just marching. She bbasically told me exactly what I already knew but I think she stole some of my brain cells in the process. Needless to say I'm not going back and still have shin pain.
