hi there, you are experiencing a colicy intermittent pain which could be originating from the GIT,premenstural or from the gall bladder or due to renal colic
. If you are constipated or have any GI symptoms then probabely you need to evacuate your bowel. The exact origin of the pain needs to be pinpointed and for that you need to get some baseline tests done. Get your routine blood and urine exam done, get an ultrasound
abdomen and if required an x-ray KUB to rule out kidney
stones. While you await these results you could use some anti-spasmodic like meftal spas
tablets to take care of the pain and once the cause is known definitive treatment can be initiated. Till then take care.
