Regarding the sensation of skin prickling?


Hello, doctor.
I would like to ask about a sensation I often experience on my skin when I'm outside, which feels like being "pricked by a needle." I sometimes think someone is poking me with a syringe, but it often seems like nothing is actually piercing my skin.
I have consulted a psychiatrist, who mentioned that it might be a hallucination.
I'm curious about how a dermatologist would explain this situation.
Thank you, doctor.

It's difficult to explain, because when there are skin issues, there are usually lesions present.
If there are none, it may be necessary to have a neurological examination to check for any issues related to the nervous system.

The sensation of "being pricked by a needle" that you are experiencing can be quite perplexing and uncomfortable. This phenomenon, often described as paresthesia, can arise from various underlying causes, both dermatological and neurological. While you have already consulted a psychiatrist who suggested that it might be a form of hallucination, it is essential to explore other potential dermatological explanations as well.

From a dermatological perspective, sensations like tingling, prickling, or even a feeling of being poked can be associated with several conditions. One common cause is nerve irritation or damage, which can occur due to various factors such as repetitive strain, pressure on nerves, or even underlying conditions like diabetes or multiple sclerosis. These conditions can lead to neuropathy, where the nerves become hypersensitive and send abnormal signals to the brain, resulting in sensations that feel like being pricked.

Another possibility is that the sensation could be related to skin conditions such as eczema or dermatitis. These conditions can cause the skin to become inflamed, leading to heightened sensitivity. When the skin is irritated, it may react more strongly to stimuli, causing sensations that feel like pricking or stinging. Additionally, conditions like fibromyalgia can also lead to heightened sensitivity to touch and abnormal sensations throughout the body.

Moreover, anxiety and stress can exacerbate these sensations. The mind-body connection is powerful, and psychological stress can manifest physically, leading to increased awareness of bodily sensations. This could explain why you might feel these prickling sensations more acutely during times of stress or anxiety.

To manage these sensations, it is crucial to first identify any potential triggers. Keeping a diary of when these sensations occur, along with any accompanying factors such as stress levels, activities, or dietary changes, may help in pinpointing the cause. If the sensations are linked to anxiety, cognitive behavioral therapy (CBT) or mindfulness practices may be beneficial in reducing the overall stress response.

In terms of dermatological care, maintaining skin health is vital. Ensure that your skin is well-moisturized, as dry skin can exacerbate sensitivity. Avoid harsh soaps or irritants that may trigger or worsen skin conditions. If you suspect that a specific product or environmental factor is contributing to your symptoms, consider eliminating it and observing any changes.

If the sensations persist or worsen, it would be advisable to consult a dermatologist for a thorough evaluation. They may recommend tests to rule out any underlying skin conditions or nerve issues. Depending on the findings, treatments may include topical medications, lifestyle modifications, or referrals to specialists such as neurologists if nerve involvement is suspected.

In conclusion, while your experience of feeling "pricked by a needle" may have been attributed to psychological factors, it is essential to consider the broader spectrum of dermatological and neurological causes. A comprehensive approach that includes both dermatological evaluation and psychological support may provide the best pathway to understanding and alleviating your symptoms.
