I Am Experiencing Strange Feelings In My Urethra/bladder. After I

I am experiencing strange feelings in my urethra/bladder. After I urinate it feels like I have wiped with sandpaper. The sensation alleviates after 5/10 minutes. I often feel like there is hot pee waiting to come out but when I do pee it feels quite normal. I often feel like my bladder is going to open on its own and I find myself tensing all my muscles in order to stop me peeing. I feel like if I relax then I'll just pee myself. I haven't leaked urine yet but I often feel like I might. I was diagnosed with atrophic vaginitis last May and have been using Vagifem but also feel like it doesn't help much and am wondering if this has any bearing on the way my bladder and urethra are feeling as I had none of these symptoms previously. It's causing me great anxiety and feel like I cannot live with this for much longer.
