[52F] With recurrent sharp lower back pain radiating to right hip and legs

What might be happening

Based on the information you've provided, here are some possible explanations for your symptoms:

• Muscle Strain or Ligament Sprain: Given that your pain is sharp and worsens with movement, coughing, or lifting, it could be due to a muscle strain or ligament sprain in your lower back. This is common and can occur from overuse or improper movement.

  • Treatment: Rest, ice, and over-the-counter pain relievers like ibuprofen or acetaminophen can help. Physical therapy may also be recommended.

• Sciatica: The pain radiating to your hip and legs, particularly on one side, suggests sciatica, which is irritation of the sciatic nerve. This can be caused by a herniated disc or spinal stenosis.

  • Treatment: Physical therapy, anti-inflammatory medications, and sometimes corticosteroid injections are used. In severe cases, surgery may be necessary.

• Kidney Issues: Given your history of kidney stones and recent stent placement, it's important to consider that kidney issues could be contributing to your back pain, although your symptoms are more consistent with musculoskeletal causes.

  • Treatment: If kidney issues are suspected, further imaging and tests would be needed to rule out any complications.

What you can do

1. Rest and Avoid Strain: Try to avoid activities that worsen your pain. Resting can help your muscles and ligaments heal.
2. Apply Ice or Heat: Ice packs can reduce inflammation, while heat packs can help relax tense muscles.
3. Over-the-Counter Pain Relievers: Medications like ibuprofen or acetaminophen can help manage pain and inflammation.
4. Stay Active: Gentle activities like walking can help keep your muscles active without overstraining them.
5. Physical Therapy: Consider seeing a physical therapist for exercises and treatments that can help alleviate your pain and prevent future episodes.

What you should look out for

Seek medical attention if you experience any of the following:

• Severe or Worsening Pain: If your pain becomes unbearable or significantly worsens.
• Numbness or Weakness: If you experience numbness, tingling, or weakness in your legs.
• Loss of Bladder or Bowel Control: This could indicate a more serious condition like cauda equina syndrome.
• Fever or Unexplained Weight Loss: These could be signs of an infection or other serious condition.
• Pain That Doesn't Improve: If your pain doesn't improve with rest and over-the-counter treatments, see a healthcare provider.

Important Note

While this information can help guide you, it is important to consult with a healthcare professional for a formal diagnosis and appropriate treatment. Your recent history of cancer and kidney issues makes it particularly important to get a thorough evaluation to rule out any serious conditions.
