Kidney Stones
Kidney stones are small hard particles that form in the kidney and are painful to pass. The deposits usually pass through urine and may be painful when passing through the thin tubes to the bladder. The stones passing can cause blood to leak into the bladder. Patients suffering from kidney stones often see blood in their urine.
Other symptoms of kidney stones include fever, vomiting, nausea, and fever.
If kidney stones are small enough, they can pass on their own with no noticeable symptoms. However, once they become larger, they can trigger a constant urge to urinate, painful urination, and hematuria.
