Left-Sided Lower Back Pain: Causes and Next Steps

Left posterior flank pain?

Hello Doctor: Recently, I have not been feeling well and have been experiencing physical and mental tension.
Two weeks ago, I had a four-day episode of head pressure and dizziness (migraine), and I occasionally feel my heart racing.
I visited an ENT specialist who diagnosed me with a possible pre-cold condition.
After taking medication, my symptoms improved significantly.
However, starting last week, I began to experience random abdominal pains and diarrhea, prompting me to consult a traditional Chinese medicine practitioner, who diagnosed me with a possible gastroenteritis.
I have been taking medication for my gastrointestinal issues for four days now, but in the last two to three days, I have felt pain in my left lower back, which sometimes radiates to the kidney area and occasionally down to the near buttock.
Gradually, I have noticed the pain extending along the groin to the testicle, and at times, I feel a dull ache in the lower abdominal triangle.
Currently, I have left lower back pain and a cramping sensation in the left testicle.
I would like your advice on whether I should finish the herbal medicine first or seek medical attention at a clinic or hospital as soon as possible.
If I do seek medical attention, which specialty should I choose, and what tests should I undergo? I hope to rule out any serious conditions, as I feel my health is deteriorating and my mental state is becoming increasingly anxious and tense.
Thank you very much for your help, Doctor.

Hello, based on your description, the previous symptoms were indeed more indicative of a cold.
However, considering the recent situation, it is highly suspected that you may have a urinary tract stone.
I recommend that you consult a urologist, as you may need to undergo a urinalysis, X-ray, or ultrasound examination.
Additionally, it is important to know if you have recently engaged in any intense abdominal exercises, such as sit-ups, as strains could also cause the pain you described.
Thank you for your inquiry.

Understanding left-sided lower back pain can be complex, especially when accompanied by other symptoms like abdominal pain, gastrointestinal issues, and discomfort in the groin and testicular areas. Based on your description, it seems like you are experiencing a combination of symptoms that could be related to several underlying conditions.
Firstly, the left-sided lower back pain could be due to a variety of reasons, including muscular strain, kidney issues, or even referred pain from gastrointestinal problems. Given that you have recently experienced abdominal pain and diarrhea, it is possible that your gastrointestinal tract is contributing to your back pain. Conditions such as diverticulitis, kidney stones, or even a urinary tract infection can cause pain that radiates to the lower back and groin area.

The fact that you have also experienced symptoms like a pounding heart and feelings of tension could suggest that your body is under stress, which can exacerbate pain perception. Stress and anxiety can lead to muscle tension, which may contribute to back pain. Additionally, if you have been experiencing gastrointestinal symptoms, your body may be reacting to this discomfort with increased muscle tension in the back.

In terms of next steps, it is crucial to address your symptoms comprehensively. Here are some recommendations:
1. Consult a Healthcare Provider: Given the complexity of your symptoms, it would be wise to consult a healthcare provider as soon as possible. Since your symptoms involve multiple systems (gastrointestinal, urological, and musculoskeletal), a primary care physician would be a good starting point. They can evaluate your symptoms and determine if you need to see a specialist, such as a gastroenterologist or urologist.

2. Diagnostic Tests: Your doctor may recommend several tests to rule out specific conditions. These could include:
- Blood tests to check for signs of infection or inflammation.

- Urinalysis to assess kidney function and rule out urinary tract infections or kidney stones.

- Imaging studies, such as an ultrasound or CT scan, to visualize the kidneys, bladder, and abdominal organs.

3. Symptom Management: While you are undergoing evaluation, managing your symptoms is essential. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, may help alleviate pain. However, consult your doctor before taking any medication, especially if you are currently on other medications or have underlying health conditions.

4. Follow-Up on Gastrointestinal Symptoms: Since you mentioned that you are currently taking traditional Chinese medicine for gastrointestinal issues, it is important to monitor how these treatments affect your symptoms. If your abdominal pain and diarrhea persist or worsen, inform your healthcare provider, as this may require further investigation.

5. Lifestyle Modifications: Stress management techniques, such as mindfulness, yoga, or gentle stretching, may help alleviate muscle tension and improve your overall well-being. Ensuring you stay hydrated and maintain a balanced diet can also support your recovery.

In conclusion, while it is essential to complete your current course of treatment for gastrointestinal symptoms, it is equally important to seek further medical evaluation for your left-sided lower back pain and associated symptoms. Early intervention can help identify any serious underlying conditions and guide appropriate treatment, ultimately improving your health and reducing anxiety about your symptoms.
