Is Numbness on One Side of the Face and Body a Stroke Warning?

Numbness in one side of the face, hand, and foot?

On the sixth day after being diagnosed with Covid-19, I experienced mild numbness on the right arm, below the knee, and from the chin to the neck when my symptoms were almost resolved.
My movements and speech are normal, and there is no pain.
The only other discomfort is dry mouth, and these symptoms have persisted for 15 hours.
Could this be a sign of a stroke?

Hello, numbness on one side of the body can indeed be a symptom of a stroke; however, it usually affects a larger area, such as the entire right side of the limbs, or even including the torso and half of the face.
Based on the extent of your numbness, the likelihood of a stroke is lower.
It has been observed that after a COVID-19 diagnosis, in addition to central nervous system disorders (such as the stroke you are concerned about), the peripheral nervous system may also be affected, leading to symptoms such as numbness and pain.
Therefore, I would recommend that if your symptoms persist, you seek consultation at a neurology clinic after your isolation period ends.
Thank you for your question.

Numbness on one side of the face and body can indeed be a concerning symptom, and it is important to take it seriously, especially in the context of a recent COVID-19 infection. While not every instance of numbness indicates a stroke, it is crucial to understand the potential implications and seek medical attention promptly.

In your case, experiencing numbness on the right side of your face, arm, and lower leg, particularly after having COVID-19, warrants careful consideration. COVID-19 has been associated with various neurological complications, including stroke. The virus can lead to inflammation, blood clotting issues, and other factors that may increase the risk of cerebrovascular accidents (strokes).
When assessing the risk of stroke, healthcare professionals often use the acronym FAST, which stands for:
- Face drooping: Does one side of the face droop or feel numb? Ask the person to smile to see if their smile is uneven.

- Arm weakness: Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward?
- Speech difficulty: Is speech slurred or hard to understand? Ask the person to repeat a simple sentence.

- Time to call emergency services: If any of these signs are observed, it is crucial to call for emergency help immediately.

In your situation, since you mentioned that your movements and speech are normal and there is no pain, it may suggest that you are not experiencing a classic stroke. However, the presence of numbness, especially if it persists or worsens, should not be ignored. Other conditions, such as transient ischemic attacks (TIAs), which are often referred to as "mini-strokes," can also present with similar symptoms and may resolve quickly but indicate an increased risk of a future stroke.

Additionally, the fact that you are experiencing these symptoms after a COVID-19 infection raises the need for further evaluation. Neurological symptoms can sometimes emerge after viral infections, and it is essential to rule out any serious complications.
Given that your symptoms have lasted for 15 hours, it is advisable to seek medical attention as soon as possible. A healthcare provider may perform a neurological examination, imaging studies such as a CT scan or MRI, and possibly blood tests to assess your condition. They will also consider your medical history, including any risk factors for stroke, such as hypertension, diabetes, or a history of cardiovascular disease.

In summary, while numbness on one side of the face and body can be a warning sign of a stroke, it is essential to evaluate the entire clinical picture. Given your recent COVID-19 diagnosis and the persistence of your symptoms, I strongly recommend that you consult a healthcare professional immediately for a thorough assessment and appropriate management. Early intervention can be critical in preventing potential complications and ensuring your health and safety.
