Welcome to Healthcare Magic
For Gall stones
of that size and also symptomatic causing you problems it can be managed by surgery only. Don't risk your health as many alternative practitioners will promise many things but it is your final choice for your standard of healthcare. It is tried, tested and proved in studies that surgery will cure your stones this time. You also need to take precautions after Surgery to prevent stone formation. You can take anti-emetics like Domperidone
to reduce vomiting
but I recommend you get admitted at the Hospital and receive fluids, antibiotics and surgery as well. After Surgery you need to eat fat free food, and avoid contraceptive
pills as well.
