They don’t have much information to give and they have limited access to information as customer service agents and you are undergoing a fairly normal processing time. What information were you expecting g to receive? Depending on the results of the medical it is either being reviewed by a healthcare worker or the application is now in background check. Be patient and you will get an approval/refusal soon. Obsessing about it will not lead to faster processing. If you have not received an answer in months then you should follow-up.
