Does anyone have experience of bad headaches on prostap. I've been given prostap to shit off cycles while I wsit for my hystetectomy.i wasn't able to cope any longer with pelvic and back pain. My back has eased within a week, but the headaches are horrible. I'm trying to alleviate with oestrogen patches but hasn't worked yet. Really scared that this is what's facing me post-hysterectomy. Does prostap mimic your body's reaction in menopause?
