Hello everyone,
I am a 20 year old male.

I have had low back pain for about four months now, and now I am having lower abdomen pain.
I have been to the doctor a few times (Urgent Care), but this upcoming Monday I will have an official appointment.
The doctor I went to believes it is a Lumbar disk problem, and it makes sense because when I bend backward, pain shoots down my right leg, so I'm pretty sure it is a nervous system issue, not a muscular one.
It's also worth mentioning that this Low back pain is the type that makes it impossible for you to bend forward.

However, with my lower abdomen, I feel discomfort now. Every time I urinate, it is slightly painful when the urine flows out, and then my lower abdomen discomfort increases a bit. I had a urine test and the doctor said my urine was clean, and he tested to see if my prostate was swollen, which it wasn't. My testicles also do not seem swollen in any way... So he simply said to wait it out to see what happens.

I am really starting to think that my lower back pain and lower abdomen pain are related, perhaps the former is culprit for the latter? And if so in what way? I had lower back pain way before the abdomen pain so it makes sense.

If anyone has similar issues or has any idea what may be going on, that will be helpful, thanks!
