I have what I'm assuming are similar intermittent pains too. No cycle just come on whenever they feel like - mostly when I'm excited or held onto my bladder contents for too long.. I'd suggest getting checked for cysts etc with a doc. Maybe ultra sound, pap test etc. Now I know I just swore at you saying that and I admit I am just unable to bring myself to have one of those but I did have the ultra sound and all was fine so... I assume it is the T competing with my natural production of whatever else in there, like overcoming my ovaries and them beginning to atrophy or waste away. My solution was to see the GP for a spesh review to have a hysto - now I'm just waiting for a surgery date. Far as I know that should solve my problem lol!
Otherwise dealing with the pain - paracetamol, ibuprofen, heat pack and curl up into a ball for a while works for me! Maybe some chocolate thrown in there to complete the cliche!
