Why Am I Experiencing Sharp Vaginal Pain, Discharge and Numbness?

Hi. I’m having vaginal nerve pain from 6 months. I’m experiencing sharp vaginal pain. Pain is not consistent and it comes and goes and lasts for 5 sec. At times when I sit on the chair or bed I have sharp pain. When I don’t urinate for long I get pain in vagina. A few minutes ago I went to poop and had to put some pressure and when I put some pressure I started having severe pain in my vagina and there was a thick white discharge like cheese. I’m still experiencing slight pain in the vagina. A month back when I was doing some jumping exercises and faced severe vaginal pain. At times I also experience numbness in my vagina, hands and legs. I had severe constipation in the past but now it’s been fine. I also experienced severe lower back pain in the past but not anymore. I was also diagnosed with PCOD. I consulted the gp to check if there is any bacterial infection or thrush and doctor confirmed that I don’t have any infection or thrush. What could be the reason for this problem.
