Update: My son went to an orthopedic surgeon today. In the wonderful world of HMO's he had to have the appointment today to get an MRI scheduled for later in the week. The ortho thinks it's the MCL rather than the ACL which could be of huge significance. MCL's tend to heal faster without surgery.
What I'm not buying is, without an MRI the ortho told him not to play until next spring. My son told him college baseball is at stake. I wasn't there. I asked my son if the ortho looks like a nerd or an athlete. He said a nerd. I told him we need to get him to a sports orthopedic specialist.
It seems rather odd and protective the ortho told my son with a knee brace he can jog straight ahead, throw and take BP as long as he doesn't do anything laterally, yet he can't play until next spring.
Next step will be the MRI. Then we have to get an opinion from a sports ortho specialist.
