Recently I having a back left down side pain and also left side down stomach pain. On that day I faced severe vomits. becoz of this I consult a doctor. They scanned my stomach and back and confirmed that I have a stones in kidney with 4 mm and 7 mm. He gave me a pain killer along with a gastric tablet. Now the pain on stomach and backside is reduced. But now am facing severe pain in testicles (penis balls). Please help me with this. Is operation is compulsory or without operation is there any chance to dissolve the stones? How the testicles pain will reduced? Am using painkiller (tramadol), but pain is not controlling. Also provide me the foods I need to take. "am a pure vegetarian"
