Hi, I have had constant
lower and upper
abdominal pain for three and a half years. Everyone told me it was in my head. Although in the past 6 months I have been diagnosed with borderline functioning gallbladder, endometriosis, adenomyosis, and interstitial cystitis. Endometriosis pain does flare up before your period, during and after. It is a sharp, knife-stabbing, ripping pain. Interstitial cystitis pain flares up before your period as well, and it is a constant sharp, or dull ache.
