Extreme adominal pain in the right side.

My symptoms are Acute stomach pain. Gas bloating. Pain in the right flank Vomiting Yellow Urine Doctor has asked for blood test ,urine test and sonography. Sonography results said 5mm by 3mm stone at the right upper ureteric just distal to pelvi ureteric junction. I belong to Mumbai but I am in Pune for the weekend, now the doctor is asking me to get admitted here in Pune. I would want to go back to Mumbai but there is a sudden sharp pain in the right flank that lasts for 2-3 hours so I can't travel with the pain. The doctor has suspected liver Infection along with stone. Therefore I am on the following pills. O2 twice daily Rabicip 20 on empty stomach Ultracet after breakfast and dinner Ondem 8mg half hour before meal Sucrafil-O half hour before each meal. All of the above medications are for my upset stomach, please advice how do I safely reach Mumbai. And start treatment for stone. Or can I start treatment here today without getting admitted.
