Hi,
Welcome to ehealthforum,
Severe abdominal cramps, dysmenorrhea could suggest underlying problems like fibroids, adenomyosis, endometriosis, STD, pelvic infections or PID, etc. The exact cause can only be made out after careful evaluation. Visit your doctor/gynecologist for further examination and investigations to look for the underlying cause for the symptoms and dysmenorrhea. Treatment as appropriate (based on the examination findings and investigation results) would be started to help you to control your symptoms. Consider being in regular follow-up and monitoring of your treating gynecologist and report any abnormal/new symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
