This thread leads me back to a question I have not found an answer to.

For those of you who are several months post injury, do you think jumping during plyometrics or the bouncing of running that leaves you feeling cruddy is slowing down your healing process at all?

I believe (I want desperately to believe) that those activities that leave you feeling cruddy may just be reminding you that you had an injury and you need to not push it to far, but are not doing any new damage or slowing your healing. Again, to use the analogy put forth by my daughter's psychologist 3-months post injury, it's just like a sprained ankle that might hurt if you jump on it months or even years after it has officially healed.

This makes a huge difference in deciding between living your life and suffering through a headache or two, or locking yourself in a closet for awhile. Of course I am referring to physical activities that are not likely to cause another blow to the head here.
