Tendinitis?

I went to a podiatrist today.  Amazingly enough the doctor was able to see me right away.  He sent me for an x-ray and even MORE surprising is the fact that the medical imaging place didn't keep me waiting forever! I've waited at that place for hours before when I needed an MRI on my back.

The x-ray didn't show any fractures or anything abnormal (thank GOD!). The doctor suspects I have tendinitis.  He gave me a shot of cortisone (ouch!) and then wrapped up my foot. The wrap consists of a pad in my arch and a whole butt-load of tape. I'm not supposed to get it wet which means showering with a trash bag. He said that it might not help the pain right away but probably will soothe it eventually.  Thing is, my foot is still killing me. And you're not going to believe it but my other foot is started to ache, this time in the arch.

I think my biggest problem might be the shoes. My doctor said that I'll need some decent running shoes and most likely some orthotics.

I'm really depressed. I finally got into a groove with this running thing and it was quickly becoming an important part of my life. And now I can't run. I can't even hobble. I hope this heals quickly because it just sucks not being able to get out and train for the half marathon. Boo.
