Weird testicle and lower abdomen pain

Soo… went through and urologist for varicocele suspicion 2 days ago. Everything came out as negative. They did blood work, urine testing and ultrasound on my stomach (not sure why not on my prostate and testicles). Sent me home with some meds and pain reliefs. Different one in a week

Symptoms: trouble beginning to pee, frequent need to pee, bone pain, back pain, had an ED for a month after the pain that made me think it’s vari - it’s fine now, excessive weight loss (-16kg for 4 months) without changing diet and even lowering activity.

Context: pain started at my testicles and lower abdomen along with ED onset, then my bones started hurting, then the difficult beginning came, then my glands started itching (derm confirmed no infections), then often need to pee started with difficulty holding it. Can’t exactly pin point when exactly all these appeared, but the order is right and it’s in the span of month and a half. Also I’ve had issues with too much gas from protein for years, but lately it’s getting me bloated with difficulty to pass it.
