Your symptoms match a wide variety of different medical conditions, including bladder problems like a urine infection. Another possibility is bladder stones that can cause sharp, crampy pain. Call your doctor if you don't get better after a day or two. In some instances for adults, these symptoms can point to something more serious like a problem with your aorta, a large artery in your lower belly. If these symptoms concern you, it's best to give your doctor a call right away.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Muscle spasms are involuntary muscle contractions that come on suddenly and are usually quite painful. Dehydration, doing strenuous exercise in a hot environment, prolonged muscle use, and certain diseases of the nervous system may cause muscle spasms. Symptoms and signs of a muscle spasm include an acute onset of pain and a possible bulge seen or felt beneath the skin where the muscle is located. Gently stretching the muscle usually resolves a muscle spasm.
Kidney stones are solid masses of crystalline material that form in the kidneys. Symptoms of kidney stones can include pain, nausea, vomiting, and even fever and chills. Kidney stones are diagnosed via CT scans and specialized X-rays. Treatment of kidney stones involves drinking lots of fluids and taking over-the-counter pain medications to medical intervention including prescription medications, lithotripsy, and sometimes even surgery.
Polymyositis is a disease of the muscle featuring inflammation of the muscle fibers. It results in weakness of the muscles which can be severe and when associated with skin rash, is referred to as dermatomyositis. Although the cause of this disease is unknown, diagnosis includes physical examination of muscle strength, blood tests for muscle enzymes, electrical tests of muscle and nerves, and conformation by a muscle biopsy. Treatment of polymyositis and dermatomyositis includes high doses of cortisone-related medications, immune suppression, and physical therapy.
Hydronephrosis describes swelling of the kidney resulting from the inability of urine to drain from the kidney into the bladder. This may be a normal variant or it may be due to an underlying illness or medical condition. Symptoms of acute hydronephrosis may include: intense flank or back pain radiating to the groin, nausea, vomiting, bloody urine, sweating, and colicky pain, which may cause the person to writhe or roll around or pace in pain.
