I act normally when I'm in pain all the time, does that mean I am not in pain? No. Likewise if i dont act normal, does that mean I'm in pain? No. I fail to see your logic. You also don't know how painful that is, because if they do in fact feel pain, then how would you know what constitutes how painful something is?Now, just to clarify - I didn't say it would "prove" anything, but I do believe that if a T can act normally with an injury like that, it would demonstrate that it is not in pain - which it should be if it could feel what we would call "pain." The opposite is not true at all though, if it doesn't act normally, it doesn't mean that it is in "pain" - it could be due to a lot of other things relating to the injury.
On topic, hope it pulls through for you Will. Good luck.
