Qualifications of medical field? Doctor or Urinalyssi lab clean up tech? LOL...j/k....
I always find it funny someone from the medical field knows how bad the injuries are, when they are not involved.
It's like if a Doctor tells his patient after many tests, that his heart is ok, but cut out the bad foods....then a friend asks a friends opinion from a medical staff, about a chest pain, and they say he / she needs open heart surgery to fix any oncoming issues.
I am not doubting you, or this person, but sorry, they don't know, we don't know, fisher doesn't know. All we can go by is what the team tells us. I choose to take their word 4 to 6 weeks.
