Yes, you can make a request to the medic that you want to visit
the same previous MO you visit before. Make a polite request and
the Medic will help you prepare the documents for the MO you saw
previously. Incase the MO you seek is no available, other MOs could
attend to you with the reported case previously wrote. So there is
noneed waste of saliva.
I only know this applies in Tekong. The rest of unit camps I think
its up to the MO/Medic to decide. BTw, are u in BMT?
