Abnormal skin sensation in the muscles below the knee?


Hello, recently while doing yoga, I experienced a pulling sensation below my knee, followed by persistent pain for several days.
Additionally, I have been feeling abnormal sensations in my muscles and skin; in certain areas, I have no sensation when pressed or touched, while in slightly larger areas, there is an abnormal feeling, and then it returns to normal.
What symptoms could this indicate? Would you recommend seeing a rehabilitation specialist, a neurologist, or another type of specialist?

Hello: It is suspected that the soft tissues around the knee joint, such as ligaments and tendons, may have been overstretched and are inflamed.
It is recommended to consult with a neurosurgeon, orthopedic surgeon, neurologist, or rehabilitation specialist.
Wishing you a speedy recovery.

More Info


Abnormal skin sensations, particularly below the knee, can be concerning and may arise from various underlying causes. Based on your description, it seems that you experienced a pulling sensation during yoga, followed by persistent pain and abnormal skin sensations in the affected area. This could indicate a few potential issues, including nerve compression, injury to the soft tissues, or even a localized inflammatory response.

When you experience abnormal sensations such as numbness or tingling, it often points to nerve involvement. The knee area is innervated by several nerves, including the saphenous nerve and the sural nerve, which can be affected by trauma, stretching, or inflammation. If the sensation is limited to a specific area and is accompanied by pain, it may suggest that the nerve in that region has been irritated or compressed.

In your case, the abnormal sensation where certain areas are numb while others are normal could indicate a localized nerve injury or irritation. This could be due to a few factors:
1. Nerve Compression or Entrapment: If there was any swelling or inflammation following your yoga practice, it could compress nearby nerves, leading to altered sensations.

2. Soft Tissue Injury: The pulling sensation you felt might have strained the muscles or tendons around the knee, which could also affect the nerves running through that area.

3. Referred Pain: Sometimes, pain or abnormal sensations in one area can be referred from another area due to interconnected nerve pathways.

Given these possibilities, it would be advisable to consult a healthcare professional for a thorough evaluation. Depending on your symptoms, you might consider seeing a neurologist, especially if the abnormal sensations persist or worsen. A neurologist can perform specific tests to assess nerve function and determine if there is any underlying nerve damage or compression.

Alternatively, if the symptoms are associated with muscle pain or if you suspect a soft tissue injury, a visit to a physical medicine and rehabilitation specialist (physiatrist) could be beneficial. They can provide a comprehensive assessment and recommend appropriate rehabilitation strategies, including physical therapy, to help restore function and alleviate pain.

In the meantime, here are some general recommendations to manage your symptoms:
- Rest: Avoid activities that exacerbate the pain or abnormal sensations.

- 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 may help improve flexibility and reduce tension in the muscles around the knee.

- Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, may help alleviate discomfort.

If your symptoms do not improve or if you experience worsening pain, weakness, or significant changes in sensation, it is crucial to seek medical attention promptly. Early intervention can often lead to better outcomes and prevent further complications.
