What does it look like compared to the other side?? I had a complete rupture of mine about 8 months ago and it's pretty obvious. There will be a gap of several inches just above your elbow where your bicep used to be. It doesn't look that way to me from your picture, but I'm not a doc. You don't need an MRI to diagnose a ruptured tendon if you can get in front of a decent orthopedic doctor. If possible, I would not advise waiting 6 months for the surgery.
