Please help ASAP

I’m 10 days pp and I’m having the worst time trying to pee. My bladder is FULL because I’ve been holding my pee because it burns and stings tremendously when I pee. I had no major tears but the doctor or nurses never really looked to what was going on down there. After my placenta was delivered I was on my own. The peri bottle isn’t much help anymore and I’m starting to cramp from my full bladder. I’m willing to try anything
