Hi, thank you for trusting HealthcareMagic.com! I m Dr. Elton Halili, General & Family Physician. I read carefully your story. Now I m giving details about your concern: - The main risk factor is hypercalciuria. Do you have members of your family which has same problem as you? Hypercalciuria means that serum cacium is normal but elevated urinary calcium. - Other factors can be primary or caused by excess ingestion of oxalate containing foods (eg, rhubarb, spinach, cocoa, nuts, pepper, tea) or by excess oxalate absorption due to various enteric diseases (eg, bacterial overgrowth syndromes, chronic pancreatic or biliary disease) or ileojejunal surgery. Other risk factors include taking high doses of vitamin C, a Ca-restricted diet (possibly because dietary Ca binds dietary oxalate) - Clitoral stimulation may be a good support, well it s known that body endorphines after stimulation are a good support for accepting the pain, but it doen t help to move the stone along urethra. you should take the painkiller for urinary colic. - If I was your doctor I would prescribe a thiazide diuretic to prevent calcium stones. If I was clear, please rate my answer as HELPFUL. Thanks again. Dr. Elton Halili
