What are the possible causes of low back pain, tingling, and numbness in the groin for two months?

Hi doctor,

I have been experiencing low back pain for two months. Sometimes, along with pain, I feel tingling and numbness in my groin and legs. Sometimes, the pain will wrap around me, and I think it is in my pelvis and genital bones. I have been to many doctors. I have had a lumbar spine CT, MRI, bone scan, and an X-ray of the pelvis. There are some minor disc bulges noted. In addition, I sometimes have increased urine urgency. My last appointment was a few months ago, where a detailed examination was performed, including intravaginal ultrasound. I complained of some additional bloating, so the doctor also did tumor markers (blood test) for ovarian cancer as a screening, which came back normal. I have read that sometimes back pain and urgency can indicate ovarian cancer. Now I am scared. Should I request ovarian cancer screening again? I have noticed some increased white discharge, clear and watery, that increases more right before the menstrual cycle. Menstrual cycles are regular and last seven days, which is normal for me. A urine culture was done yesterday, and it was also negative. No weight loss has been noted. Please advise.

Thank you.

Hi doctor,

Thanks for the reply.

My maternal grandfather had colon cancer. It was caught early, and he is fine. Other than that, no history.

Thank you.
