  • I was diagnosed in April of this year with stage Ia invasive duct carcinoma. I had a wide excision and then received 19 sessions if whole breast radiation. I started 10 mg of tamoxifen every other day two months ago. I am participating in a research study called “low Tam. “ Since being on tamoxifen, I have had pelvic pressure, low black pain, and maybe interstitial cystitis or just a bladder pain syndrome. Any advice or help for me?
    Thanks

    @enojada check out interstitial cystitis association web site. I believe they have a list of doctors that work with this condition (I had it for years before bc dx- hasn’t been exacerbated by lexatrole) If you are dx’d with IC/painful bladder, A low dose tricyclic antidepressant like amitripyline or nortriptyline can help (has worked for me anyway). Dosage is lower than what would be used to treat depression when these meds are used to treat pain. So something worth discussing with doctor if you get the diagnosis Physical therapy for pelvic floor problems also can be helpful and some physical therapists specialize in this

    Check out if different foods or drinks make symptoms worse— ie things that are spicy or acidic. Coffee can really trigger pain (I can drink cold brew as it’s less acidic). Different people have different food and drink’s sensitivities

  • Thank you for the advice anjou7. I will be seeing medical oncology on October 3 and I will discuss with them. My gynecologist did mention pelvic PT. I don’t think the irritation is coming from foods, I’ve looked at all the triggers and I’m not a coffee drinker or a spicy food eater.
