What u can do.bring this medicine along and see new government hospital gp.  Normal private doctor practise is expensive.  Cos they are using non generic for patient during the first few sessions until the patient turn better and they change to generic drug for cheaper alternatives.
Any physiatric treatment normally minimum 3 months to be sure and a few follow up down the road.
So if u can't afford private go for government hospital.
Don't take that the doctor want your business and trying to drag  ur treatment. U are not in fever and not antibiotic n paradol can settle it.
