So sorry to hear about that and how they treated you! You definitely do need to find another venue for treatment, but meanwhile, take a deep breath. Try to calm yourself because 3cm is a very small tear. It will do more harm to you too, for you to get into a panic mood. Appeal to your head and think. Do research, read a lot and seek a new dr. Meanwhile eat healthy, continue to do daily routine, trust that God has this in control. You are going to be ok; you got this. Will pray for great resolution for you.🥰🙏🏼
