Hello and hope you are doing well.
A complete medical evaluation is necessary for correct diagnosis and management of your condition. Few common conditions which can cause calcium in urine are kidney stones and hyperparathyroidism. The common signs and symptoms seen with kidney stones are excess calcium in the urine, severe one-sided back, flank, abdominal and groin pain, pain when urinating, blood in the urine, nausea and vomiting, an unrelenting urge to urinate and, in few cases, fever and chills. In hyperparathyroidism there is hypercalciuria, frequent urination, bone pain, joint pain and loss of appetite. A complete evaluation and tests like blood urea, creatinine, urine examination and ultrasound kidney may be helpful for determining the exact cause. Management will depend on the cause. Consult a Urologist for further evaluation and management.
Best luck and regards!
