I was diagnosed with kidney stones in October and then I was on a medication (allopathic) for 3 weeks and when I stopped taking the medication the pain and vomitting returned. So then I started taking homeopathy medicines for the same but now again after a month even on being on medication I'm experiencing pain. How long does it usually take for a kidney stone to pass? Is it okay if it's been 2 months and it still didn't pass?
