Hello.I am Allopathic doctor, so I can tell you medication only related to that field.
But first I need your complete reports (rft
lft vit d pth 24 hr urine)
Get a ncct kub (dual energy) to get the stone type
Syp K Cit 2 tsp TDS is very good to improve your urine ph and decrease excretion of oxalate.
However you will need home monitoring of urine ph with strips (commonly available in chemist shop) to control the dose of Syp k Cit so that your urine ph is the right range.
Also are you a diabetic?
