Adenomyosis is a condition where endometrial tissue grows within the myometrium of the uterus, causing uterine enlargement and heavy, painful menstrual periods. Secondary dysmenorrhoea is characterised by menstrual pain that develops after a history of pain-free periods, typically due to underlying pathology. Adenomyosis commonly presents in multiparous women in their late 30s and 40s with progressively worsening menstrual pain, making it a classic cause of secondary dysmenorrhoea.

oral mifepristone. Mifepristone is a progesterone receptor antagonist → weakening of attachment to the endometrial wall + cervical softening and dilation + induction of uterine contractions
48 hours later, misoprostol (vaginal, oral or sublingual) unless the gestational sac has already been passed. Misoprostol is a prostaglandin analogue, binds to myometrial cells → strong myometrial contractions → expulsion of products of conception
if bleeding has not started within 48 hours after misoprostol treatment, they should contact their healthcare professional

Furthermore, Crohn's disease is characterised by transmural inflammation which may result in complications such as strictures, abscesses or fistulas, which could also contribute to a palpable mass.

Levodopa vs dopamine agonist in PD
Finally, a dopamine agonist, such as pramipexole or ropinirole, could be considered an alternative initial treatment option for some patients with Parkinson's disease; however, it is less likely to be offered initially in this case. Dopamine agonists directly stimulate dopamine receptors, mimicking the effects of dopamine. They are generally used for younger patients or those with mild symptoms as they have a lower risk of motor complications compared to Levodopa. In this scenario, the patient's symptoms are significantly affecting his ability to work and his quality of life, making Levodopa the most appropriate initial treatment option.
103
Wallenberg vs webers
