Dull pain in the left flank?
Hello Dr.
Lee,
Last month (on October 9), I had a motorcycle accident where I fell on my left side.
At the time, I was able to stand up on my own.
After returning home, I noticed bruising on my left lower back, but it did not significantly affect my daily life.
It has now been over a month, and the bruising has mostly disappeared, but I still experience occasional mild pain, which does not greatly impact my daily activities.
I would like to ask Dr.
Lee what symptoms this might indicate and whether I should go to the hospital for an ultrasound for further examination.
Thank you, doctor!

It may be a muscle injury; you can go to the hospital for an ultrasound examination to monitor the recovery progress.

Hello! Thank you for reaching out regarding your persistent left side lower back pain following your fall on October 9th. It’s understandable to be concerned about lingering pain after an injury, especially when it impacts your daily life, even if only slightly.
Based on your description, it seems that you experienced a bruise on your left side after the fall, which is a common occurrence when falling onto a hard surface. The fact that the bruise has mostly disappeared but you still experience occasional pain suggests that there may be underlying soft tissue damage, such as a strain or sprain of the muscles or ligaments in that area. It’s also possible that there could be some inflammation in the muscles or connective tissues surrounding the lumbar spine, which can cause discomfort even after the initial injury has healed.
Injuries to the lower back can involve several structures, including muscles, ligaments, tendons, and even the intervertebral discs. Given that you were able to stand and walk immediately after the fall, it’s less likely that you sustained a serious injury such as a fracture or a herniated disc, but these possibilities cannot be completely ruled out without further examination.
Here are some potential causes for your ongoing pain:
1. Muscle Strain: The muscles in your lower back may have been strained during the fall, leading to lingering discomfort. Muscle strains can take time to heal, and even after the initial pain subsides, residual soreness can persist.
2. Ligament Sprain: Similar to muscle strains, ligaments can be stretched or torn during a fall, which can lead to pain and instability in the affected area.
3. Contusion: A bruise (contusion) can cause pain even after the visible signs have faded. The underlying tissue may still be healing.
4. Nerve Irritation: If there was any impact on the spine or surrounding structures, it could potentially irritate nearby nerves, leading to pain that may not be directly related to the injury site.
5. Referred Pain: Sometimes, pain can be referred from other areas, such as the hips or pelvis, especially if there was any compensatory movement following the injury.
Regarding your question about whether you should seek further evaluation, it would be prudent to consult a healthcare professional if the pain persists or worsens. An ultrasound or MRI may be beneficial to assess the soft tissues and structures in your lower back more thoroughly. These imaging studies can help identify any hidden injuries that may not be apparent through physical examination alone.
In the meantime, consider the following self-care measures:
- Rest: Avoid activities that exacerbate the pain.
- Ice Therapy: Applying ice to the affected area can help reduce inflammation and numb the pain.
- Gentle Stretching: Once the acute pain subsides, gentle stretching and strengthening exercises may help restore mobility and prevent future injuries.
- Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation.
If your symptoms do not improve or if you experience any new symptoms, such as numbness, tingling, or weakness in your legs, it’s essential to seek medical attention promptly. Early intervention can prevent further complications and aid in a quicker recovery.
I hope this information helps you understand your condition better and guides you in making informed decisions about your health. Wishing you a speedy recovery!
