Pain in the soles of the feet during urination?
Hello Doctor: Since the morning of March 13th, I have been experiencing severe stabbing pain in my left foot while urinating, similar to neuropathic pain, located near the center of the forefoot close to the big toe.
I visited an internal medicine doctor for a urinalysis and blood tests, and the only abnormal finding was a cholesterol level of 244, which is slightly elevated.
I then went to the orthopedic department at Tamsui Ma-Jia for a consultation, but the doctor was also uncertain about the cause and only arranged for further examinations.
I would like to ask what might be the cause of this, and whether I should see a neurologist or a urologist? Thank you.

Dear Mr.
Hsiao,
You mentioned that "there is a sharp pain in your left foot when urinating," which may suggest radicular pain, particularly from the sciatic nerve.
I would like to know if your urinalysis has ruled out the presence of occult blood.
If it has been ruled out, it would be advisable to consult a neurologist first.
Peripheral nerve issues can typically be assessed using electrophysiological studies for diagnosis.
Nerve conduction studies measure the conduction velocity and waveform of large fiber nerves, while electromyography (EMG) assesses the muscle response in the areas innervated by the nerves.
I recommend that you visit a neurology outpatient clinic for further evaluation.
Thank you for your inquiry, and feel free to discuss any related questions!
Wishing you good health and peace,
Dr.

More Info
The symptoms you're experiencing, specifically the sharp pain in your left foot during urination, can be quite perplexing and may suggest a neurological issue or a possible connection between the urinary system and the nervous system. While it might seem unrelated, the body’s systems are interconnected, and pain can sometimes manifest in unexpected ways.
Firstly, it’s important to understand that pain during urination is typically associated with urinary tract issues, such as infections or inflammation. However, the fact that you are experiencing sharp pain in your foot simultaneously raises the possibility of a neurological condition. This could involve nerve compression or irritation that is causing referred pain, where pain is felt in one area of the body due to an issue in another area.
One potential explanation for your symptoms could be a condition known as "referred pain." This occurs when pain is perceived in an area of the body that is not the source of the pain. For example, nerve pathways can sometimes overlap, leading to confusion in the brain about where the pain is originating. In your case, the nerves that supply sensation to your foot may be affected by an underlying issue that is also related to your urinary system.
Another possibility is that you may be experiencing a condition such as "tarsal tunnel syndrome," where the posterior tibial nerve is compressed as it passes through the tarsal tunnel in the ankle. This can lead to symptoms such as sharp pain, tingling, or numbness in the foot. If this nerve is irritated or compressed, it could potentially cause pain that coincides with other bodily functions, including urination.
Given your elevated cholesterol levels, it’s also worth considering vascular issues. Poor circulation or nerve damage due to high cholesterol could lead to symptoms in the extremities. However, this is less likely to cause pain specifically during urination.
To address your question about which specialist to see, it would be prudent to consult a neurologist first. A neurologist can evaluate your symptoms in detail, perform necessary tests such as nerve conduction studies, and determine if there is a neurological cause for your pain. If the neurologist finds no neurological issues, they may then refer you to a urologist to investigate any potential urinary tract problems.
In the meantime, keeping a detailed diary of your symptoms can be helpful. Note when the pain occurs, its intensity, any activities that seem to exacerbate it, and any other symptoms you may experience. This information can provide valuable insights for your healthcare providers.
In summary, while your symptoms may seem disconnected, they could be related through a neurological pathway. Consulting with a neurologist is the best course of action to determine the underlying cause of your pain and to receive appropriate treatment. If necessary, they can guide you to further specialists based on their findings. Remember to prioritize your health and seek medical attention promptly to address these concerning symptoms.
