Hello and thanks for the query
I have read your query with diligence. Your pain is most likely to be a Renal stone pain you need to be investigated for that. Get your urine routine examination done with sonography
of abdomen. X-ray KUB also helps in detecting the stone is done empty stomach. Consult your doctor and get your investigation done as per the advise. Meanwhile take plenty of water. Urinary alkalizer if burning maturation is present. Take anti-spasmodic drugs to reduce the pain.
Other disease which can cause pain are muscular spasm. Gall blabber stone. But these are associated with nausea
. So consult your doctor and get to a diagnosis.
Hope this will help you out.
