Maybe someone can help me. For the past four months I have been experience really severe pain in my lower right leg. I have had shin splints before. I did the anti inflammatories, icing, rest, return to running slowly... etc. The pain persisted. The pain hurts when I run for longer than 5 minutes and hurts the duration of the run, and continues hurting the whole day. I had a bone scan and MRI done. THe MRI concluded there were no stress fractures (which surprised me because my pain is very localized--just a two inch patch on my mid tibia that hurt to the palpitated touch). The bone scan showed activity and inflammation in my knee and ankle. The PA I went to told me that it is tendonitis in my knee with referred pain. I just want to be sure. I only feel pain in my knee when I'm actually running. After I'm done running, the pain is localized in my tibia. Has anyone experienced something similar? It is actually patellar tendonitis? It just seems weird to me that a injury in my knee doesn't really hurt my knee that much but severly hurts my shins...
