I'm sorry to hear about the pain and difficulties you're experiencing.

Your symptoms of prolonged low back pain and difficulty standing, along with a history of ejaculation problems, suggest that you should seek a thorough medical evaluation as soon as possible. These symptoms could be related to nerve or musculoskeletal issues, or possibly linked to prostate or urological conditions, especially considering the previous ejaculation problems.

What you should do:

• See a specialist doctor promptly: A consultation with a urologist and possibly a neurologist or orthopedic specialist is important to identify the cause of your symptoms.
• Diagnostic tests: Your doctor may recommend imaging studies like an MRI or X-ray of the lower back, and possibly urological evaluations to assess prostate health.
• Pain management: Until you see a doctor, avoid activities that worsen your pain, and consider over-the-counter pain relief if appropriate.
• Medication review: If you have been using medications such as Silodosin (used for prostate issues and known to cause ejaculation problems), inform your doctor as this might be relevant to your symptoms.

Important:

• Do not delay seeking medical care, especially since your pain limits your ability to stand.
• If you experience worsening symptoms such as numbness, weakness, bladder or bowel control issues, seek emergency care immediately.

Please consult a urologist and an orthopedic or neurologic specialist for a comprehensive evaluation and personalized treatment plan.To narrow down potential causes, we will need some more information.Could you please tell me your age and gender?
