Julie's website is "virtual." You don't need to go anywhere. Take some time and watch her 9 videos. They cover pelvic floor issues related to IC. Americans are also under a government health plan. No different anymore really. (I know Canadians). I have to BRING my issues to the doctor and she refers me to the specialist. Sometimes I go outside because it is too slow or their approved coverage doesn't extend to my need. Of, course, that is why THIS group exists.
I see you are frustrated and defeated. The truth is that if you want to be relieved of any health problem it is you who will need to do the homework. The doctors no longer do that. They only have time to treat the obvious. Although they are skilled -- they no longer "dig" for the answers to our problems. Get a second opinion. Go to a different type doctor if you are not resolved. Appeal your doctors decisions to the plan. but you will need to do homework.

Well, we in the USA, are often subject ti the whims of our health insurance policies, and still far too many who cannot get health insurance through employers, or have such high deductible & co-pays they are unable to fully use it. And there's a ream of paperwork for referrals, prior authorizations and pharmacy benefits management rules and loopholes to be exploited the corporate entities to deny coverage--in essence they are not denying care, just refusing to pay for it.
Back to your pain issues--
If you are female and particularly in peri-menopause & menopause, but also for post partum women, hormonal changes can significantly impair our vulva, and urethra, as genitourinary syndrome of menopause (GSM, or GUSM, or previously, vaginal atrophy) causes the tissues to thin out, become more likely to have microtears from wear and tear of life, etc.
So, discuss estradiol or similar treatments with primary care--should be a no brainer, but....You can get estradiol cream to apply topically, or a suppository form. Treatment is usually 2x a week. But first couple weeks might need daily dose. Mark Cubans costplusdrugs.com carries generic cream at a reasonable cost. It is so worthwhile even if one is no longer sexually active because UTIs can be significantly diminished in aging women. And oftentimes it seems it's neither a UTI nor IC but the GSM that is causing the pain & difficulty. The Menopause Society has some resources and physicians listed. There are a number of women physicians on Instagram and Substack who are trying to do more for women across the board with respect to medical care and research I to our health needs.
