Injury upon injury

Talking to my Mom on the phone today, I learned that my Dad had an accident while biking home from work yesterday. Something happened to his chain and before he could get his foot underneath him he took a tumble off the side of the road, which had a shoulder 12 inches high. He ended up re-injuring the shoulder on which he had surgery this winter.

At his doctor's appointment today, he was unable to get a definite answer as to the extent of the injury, but there's a possibility that the tear that the surgery repaired has been torn again. Ugh. He's to go back in a few weeks when the inflamation has gone down and he'll have an MRI done. Ugh ugh.

While I'm extremely grateful that nothing worse happened (like falling under the wheels of a vehicle) I'm still worried.
